Hi All,
How can we obtain the GMT Offset value (+2, +5 ...) for a date without
changing the computer's clock.

Thanks all,
ibrahim

I'm not sure what you mean by "Offset value", but I assume you want to know
the number of hours difference between local time and UTC.  To do this, you
can use GetTimeZoneInformation() and retrieve the 'Bias' member of the
TIME_ZONE_INFORMATION structure.  Then divide by 60 (Bias is the number of
minutes difference between local time and GMT).

Does this help?
