The elapsed time between two time values are not affected by DST.

Dim StartTime As Date
Dim EndTime As Date
Dim ElapsedTime As Date
EndTime = TimeSerial(18, 0, 0) ' 6:00 PM
StartTime = TimeSerial(12, 0, 0) ' Noon
ElapsedTime = EndTime - StartTime ' 6 Hours
Debug.Print Format(ElapsedTime, "hh:mm:ss")


Where and in what way would DST possibly affect the calculation above?

We use excel to track the number of hours / minutes from the placing of a
order and when it was complete. It appears that excel does not take in the
new US daylight saving time into affect when looking at elasped time or
time
range calculation.

Are there any patches being planned by microsoft specifically for excel or
access or sql for use with the new daylight saving time? (So that from
Noon
on Saturday to Noon on Sunday will count as 23 and not 24 hours)
