ASP Access DateTime Comparisons

I am having some difficulty with this although it will probably seem obvious when someone answers.

I have a field in an Access database which holds a ClosingDate in format dd/mm/yyyy

There is also a standard closing time of 16:00 hours.

On my ASP page how can I check that the current data and time is prior to the Closing Date and Time.

for example:

If FormatDateTime(rsMyRS.Fields.Item("ClosingDate").Value ~plus the time of 1600~, vbSomeFormatDate)
< FormDateTime (Now(), vbSomeFormatDate) Then

'Do Something

End If
