Enforce code only within a given time frame?

[cure4glass1]

I have a spreadsheet with code that will not allow a save unless an entry is made into a certain cell.However,I only need to enforce this code when the last entry is made for the previous day, which is done between midnight and 3 am.Any ideas on the best way to accomplish this?
Thanks in advance-Greg
