Hi Peter,
Thank you so much! This is exactly the piece of information I have been looking
for. However, my investigation of the GetTimeZone method in the Windows unit
exposes only a few of the records of the Microsoft _TIME_ZONE_INFORMATION type.
I failed when I tried to access the methods and properties of the class
TimeZoneInformation exposed in the library file "mscorlib.dll." But, I could
query the registry keys:
"HKLM\System\CurrentControlSet\Control\TimeZoneInformation\" and
"HKLM\Software\Microsoft\Windows NT\CurrentVersion\Time Zones\"
to retrieve the currently set time zone information on the machine. Considering
the fact that a record key doesn't always represent the same chunk of
information in all versions of Windows, I think it is more accurate to query
the registry. But, thank you. I just wanted to share my findings on the forum.
