General :: Formatting Time Conversion - Calculated Elapsed Time
Dec 3, 2013
Formatting issue regarding elapsed time calculated using DateDiff().
I understand that you can specify the output value for DateDiff(). In my case I have chosen "n" for minutes. Each result in my query shows the correct calculation in terms of minutes.
[PunchIn] = 11/23/2013 8:11:28 AM
[PunchOut] = 11/23/2013 5:43:30 PM
[ShiftLength] =DateDiff("n", [PunchIn],[PunchOut]) = 572 minutes.
Now when I try to format the result in terms of H:MM (be it in a form or a report) I get varied results. I'll illustrate an example below:
=Format(([ShiftLength]/60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 10.32 Not correct
=Format(([ShiftLength]60),"0") & "." & Format(([ShiftLength] Mod 60),"00") Returns 9.32 This is correct but I need my result to be in the form of a decimal such as my next example
=([ShiftLength]/60) Returns 9.53333333. Getting there but how do I have this result only show two decimal points 9.53?

Here is the table info I'm working with:
class status changeby changedate statustracking
INCIDENT-RESOLVED- Person A-2/20/2014 9:05 -
INCIDENT-RESOLVED-Person b-2/20/2014 11:57 -
INCIDENT-QUEUED-Person b-2/19/2014 13:57 - 01:24:08
INCIDENT-QUEUED-Person c-2/19/2014 15:21 - 19:29:58
INCIDENT-QUEUED-Person c-2/20/2014 10:51 - 01:06:00
I need to be able to add the statustracking time together per person per status (so person c would need 19:29:58 + 01:06:00 added together). Access keeps trying to add dates to the field or reconfigure the numbers to date ime or zeros if I use any of the data type other then Memo or text.

I have a working dB which can calculate a shift duration and sum total all shifts worked within a period for the purpose of producing a labor report for payroll. I have successfully used the DateDiff function and converted the minutes to HH:MM on my form and reports. Now I want to calculate elapsed time for a specific period within a shift, I'll call it OtherHours and I am aiming to calculate a portion of time that meet the following conditions below. I am using field names of [PunchIn] and [PunchOut] and both are of type General Date.
IF [PunchOut] ISNOT Saturday,Sunday
EXIT FUNCTION
ELSE
IF [PunchOut] ISNOT Between Midnight and 0559 hours
EXIT FUNCTION
ELSE
DATEDIFF ("n", <MIDNIGHT>, [PunchOut])
My thoughts are to solve the DateDiff portion and then figure out how to apply the conditions within the IF statements.

In my form I have a calculated field that works out the time elapsed for a job, worked out as the QTY/RUN RATE which gives me the time in hours. However I couldn't format the box as a date/time, as it is a calculation and the times may go over 24 Hours which results in the date/time giving me something like 31/12/1899 16:00 for example.
I've got around this now and I've formatted the results as HH:NN:SS using a public function in a module, but the problem is this is now stored as a text field. I've tried setting this to a number field but the formatting doesn't carry over. I've tried setting a custom format in the table as HH:NN:SS but then all I get is just a bunch of 0's, no calculation results.
So how to format this as a number field properly?
Also for any extra information:
- I know you're not supposed to store calculated results, but this is slightly different, the calculated field is a standalone text box and the bound field is a formatted text box.
- The reason I have to store the calculated results is because my boss wants to eventually see a chart of the total hours of jobs each day, hence why I'm asking if this can be done as a number field.

Hi
Newbie to Access so bare with me.
I am making a database to log working hours onto for different contracts I work on.
The fields I am having a problem with are "start date and time", "End date and time" and then "Elapsed time"
I need to populate these fields in the format 13/08/2006 17:20 etc.
How do I set the date/time format to do this and then how do I calculate the elapsed time in days,hours and minutes ? (perhaps just hours might do instead of days and hours) I also need to take out non working time ie 6pm through to 8am to make the calculations correct.
Everything else works fine bu I am stuck on this now.
Thanks.

I am trying to build a form to calculate time elapsed/time difference.
Example if one turns up for work at 1900hrs (start) and ends his duty at 0200hrs the next day (end), how much time has elapsed? I am trying to use this argument :
Elapsed: IIf([end] > [start], Format([end] - [start], "Short Time"), Format(1 - [start] + [end], "Short Time"))
Unfortunately, I am not grtting the desired result. Could anyone please assist?
Thanks

I have been trying to help a user calculate elapsed time. I referenced the GetElapsedTime from the following Microsoft article
http://support.microsoft.com/kb/210604/
It displays ok on a form or inserting on the detail in a report like it suggests
but the user would also like to total up the elapsed time on the report. Not sure how to do that with the way this function is built.

I am creating query that calculates time interval so that this is used to calculate pay. Employees clock in at [time_in] and clock out at [time_out]. Sometimes time_out is on the next day of time_in.So if is substract time_out - time_in I will get a negative number.I am therefore using the following formula to extract the time interval; Interval: Format([time_out]-[time_in],"Short Time")
this gives out a result such as 3:30 when in fact I would need 3.5 to calculate pay by multiplying with rate.How do I convert 3:30 to 3.5. From the searches I get that I need to multiple 3:30 by 24. But when in put done in the query Interval: Format([time_out]-[time_in],"Short Time")*24

I am currently in the process of creating an Employee Database. I have a 'staff information' table with several fields, one of which is a 'contracted hours field'. I have a spreadsheet linked to this database and therefore require this field to be formatted correctly in hours and minutes. For example...I wish to store a decimal time of 37.5 as 37:30.

I have a database with two fields [RECEIVED] and [DISPATCHED] which unfortunately are text fields which I can't change (linked via ODBC). Time is entered in these fields as military time.
I created a query with [DISPATCHED]-[RECEIVED] which works unless the time spans different hours. Example 1605-1555 returns 50 instead of the correct 10.
Any idea how I can use a query to calculate this accurately. I am an intermediate user. Any help appreciated.

I have a query that calculates elapsed time from TimeIn and TimeOut formatted to hours and minutes. I need be able to mulitply the elapsed time by the hourly wage in order to find the hourly pay.
How do you format the time so that it is compatible to multiply with the wage?
My SQL statement is below. Thanks for your help.
SELECT tTimeCards.ValetFirstName, tTimeCards.ValetLastName, Format([TimeOut]-[TimeIn],"hh:mm") AS HoursWorked, [HoursWorked]*[tValets]![HourlyWage] AS HourlyPay
FROM tValets INNER JOIN tTimeCards ON tValets.ValetID = tTimeCards.ValetID;

I have been trying for about 8 hours to calculate elapsed time between two fields into a third field in Access 2007. Unfortunately, the expression
IIf(IsNull)([Final Suspense]),DateDiff("d",[Routing Status Date],Date()),DateDiff("d",[Routing Status Date],[Final Suspense]))
is not working. Image enclosed....

I have a large table with a number of fields. I have written the query that I want but can't quite work out how to get it to do the main thing I need. I have several fields that I need to generate in the report but what I want it based on is the field called Date Approved.
When the Date Approved has been Active for more than 4 weeks I want to pick it up in the report. I don't want to set a date to start from but pick up everything that has passed 4 weeks in "Date Approved".

I have placed a combo box on the form. The combo box displays time from 7:00 to 13:00 in the same format. There is a label adjacent to combo box that converts the time selected in the combo box to IST. the code for this is like this
Dim arrLoginTime() As String
arrLoginTime = Split(cmbLoginTime, ":")
lblIST.Caption = Format(TimeSerial(CInt(arrLoginTime(0)), CInt(arrLoginTime(1)), 0) + TimeSerial(10, 30, 0), "hh:mm AM/PM") & " IST"
If I select 12:00 it converts correctly and displays 10:30PM IST. When I select 13:00, it displays 11:30 AM IST instead of 11:30 PM IST.
Any idea how is it behaving and what to do to correct it?

I am using MS Access 2000 and have imported some raw data one of the rows of data shows a time but displays this as a general number ie; 1246 or 745 is there any way I can convert this number into a time, 24hr would be nice, so 1246 displays as 12:46 and 745 displays as 07:45 or 1530 displays as 15:30 ?
Best Wishes

I have a text string in the following format "00:09:10". Is there a function I could use that would convert it to HH:MM:SS?
I have been asked to calculate an average of time spent on a certain task and it is stored as text. Does anyone have suggestions on how this could be accomplished?

I have an application with a backend db on PC 1, and the same application on PC 2 linked to the backend db on PC 1 via the network.
The link works fine but the time formats are different.
On PC 1 the time format is shortime and displays as it should i.e. in 24 hour clock format
However on PC 2, opening the same database via the network, the time format is still shorttime but when you read the time within the code it comes out in AM/PM format. Also, when the defaul tiem should be #20:00:00# but this changes to #8:00:00 PM#
Weirdly though, when you just open the table, the times are in the correct shorttime format.
Guessing, it must be a setting within the main core of Access 2003 that is different between the 2 instances?
Any ideas?

Hi all,
i am fairly new to the use of VB so (1) I am not sure if this is possible and (2) i wouldn't know where to start really so any help is greatly appreciated. I guess that in order to achieve whet i eventually want to (assuming it is possible that is) will be based on using some element of DateDiff. I have searched the forum and whilst i now have a basic understanding of the DateDiff function, i could find nothing that would help solve my problem.
On my form - which is a continuous Form displaying a number of the same type of records - i have a number of fields including InvoiceDate and TaxInvoiceDate. What i have been trying to achieve is the following:
1. Should the number of days since the InvoiceDate and the current date exceeds a certain i would like to format the InvoiceDate field, for example, if more than 30 days but less then 45 days have elapsed then the field could be this and if greater than 45 days then this. This indicates overdue accounts, with me so far? This i have managed to implement this using Conditional Formatting.
2. However, if a date is included in the Tax Invoice Date (meaning that the account has been settled / paid) i want to return / leave the text normal colour / font. This second point i guess will not be achievable when using conditional Formatting?
So, i believe that in order to achieve both points i need to use VB? If so, can anybody help me by suggesting suitable coding and where on the form / fields this code should go.
(Grovel Time) I should add that it only recently that i started using Access and developing my own databases but i have learn't so much from this forum - who knows sometime in the future i may also be able to partake by answering queries myself;)
Regards
Alan

Apologies if this has been asked before but I have a problem with being able to format a field to accept an hours and minutes value where the hours is likely to be greater than 23.
I have a form that is related to the number of hours that people spend in respite care. Entry and exit dates are provided in a standard way - date and time - and I have a calculating field that calculates the number of hours and minutes that a person spends at the respite centre based on the entries made in the entry and exit fields.
Because the calculating field is based on a module and I need to have the calculated amount included in the table, I have set up a VBA code to copy the result of the calculation into a controlled field elsewhere in the form.
However, I also need the form to do a simple calculation whereby hours spent away from the centre are subtracted from the total hours calculated by the module, so I need the copied value to be in a format where the calcualtion is able to be performed.
In a nutshell I guess I am looking for a time format for the field that will allow the recipt of a value greater than 23 hours.
Of course perhaps I need a more sophisticated VBA script to perform the calculation behind the scenes but I admit to not being particularly at ease with VBA scripting. If anybody has any suggestions about either a format or a suggestion for a VBA script, I would be very appreciative.
Thanks in advance,
Chris Montgomery

I have a time/date field. The format for the field is short time hh:mm I created a Private Sub for when the field is double clicked the time is populated.On Double Click:
Private Sub Time_of_Call__DblClick(Cancel As Integer)
Me.[Time of Call:] = Time()
End Sub
It works great. I double click the field and "poof" the time appears. My problem is when the time appears it is in hh:mm:ss..I need it to be in 24 hour/ military time.
