I am developing a job costing timesheet application where techicians enter their time and show how each block of time is applied to what job and general ledger code. The main file is TimeSheetEntries.fp5, where each block of time is a separate record (no repeating fields). If it matters, this file has a serialized, non-repeating key field called EntryID.

I'd like for the default entry for the "StartTime" field to be the "EndTime" field from the previous record, to minimize the data entry burden on the technicians.

Thanks in advance for the help.

This is easy to do with a script, and if you used a plugin like Events <http://wmotion.com/events.html> you could trigger the script automatically when a record is created. Otherwise, you'll need to trigger the script with a button or the Scripts menu.
