I have a column of time values in a dbf file from a GPS unit. The time
values are in military time format, i.e. "16:34:27" and they are written to
the dbf as string values. I'm having a hard time figuring out how to do
simple subtraction with them. Should I store them as String values or as
Variants? I've tried both with little success. Any help greatly
appreciated. Thanks!

You could store them as Date... Subtraction can be performed on Dates and
you can do date/time formatting with it too.

Sub test()
Dim dtm1 As Date, dtm2 As Date

dtm1 = CDate("12:30:00")
dtm2 = CDate("16:34:27")

MsgBox Format(dtm2 - dtm1, "hh:mm:ss")
End Sub
