Tables :: Time Stamp On Split Tables

I have access that is required to be accessed by multiple users and register their activities which is reflected with the tables in the background and form sends also the time that they are putting their activities.

So i split the tables and put them in a share folder in one of the PCs. however, the problem is about the timing and dates is not correct usually, and i found out some of the PCs their dates are not on sync. I asked and found out sometimes it is required to change the timing in their PCs.

Therefore, i was wondering instead of fetching the timing from their PCs why not to put the timing of share PC (i.e. timing/Date of the share PC which has the splitted tables)

so can i do like this:

User PC: (Form1) & user activity => Share PC: (Split table) & take time of the share

How can i do that?!
