I created 4 test-files on Windows and MacOS-Machines
with the system-time set to the 01.01. and to the 01.05.2006:
"Mac Winter 18.52.rtf" means:
- File created on a mac
- At "Winterzeit" (01.01.2006)
- At 18:52
"Win Sommer 18.27.txt" means:
- File created on a Windows-Machine
- At "Sommerzeit" (01.05.2006)
- At 18:27
Then I ran the following statements on both machines with different
system-time-settings:
theFile.Name+" "+Format(theFile.ModificationDate.TotalSeconds, "#")+"
"+theFile.ModificationDate.YYYYMMDDHHMISS+" "+Format
(theFile.ModificationDate.GMTOffset, "+#")
Macintosh, 01.01.2006, "Winterzeit"

Any Ideas how I can compare those file-dates???
Thanks,

Yes! Both computers shows the same time. The Mac is set to "CEST,
Berlin" and the Windows-Machine is set to "Daylight Time,
Berlin" (hopefully the same). Both machines are getting the actual
time from a time server
Is that problem in any way related to RB? Or happens that to any file
you modify on your PC or your Mac?
And if you have access to both computers: couldn't you just modify a
file while watching the clock on your wall and on your PC/Mac and
then compare these dates with the file's modified date?
And if that problem is related to RB (you didn't specify your
version): In RB2006r1 a (somewhat misnamed) property GMTOffset was
added "secretly" to the date class. So I could be possible that when
creating a date the local time might be wrong on the PC. But why only
for the modification date? Do you change the GMTOffset value anywhere?

As I recall, most versions of Windows (possibly changed in XP) store
file times in local time. These need to be converted according to
some bizarre algorithm.
The Mac - and all Unix systems - store times in GMT and convert for
display.
