Re: Converting from GMT

Tech-Archive recommends: Speed Up your PC by fixing your registry

You can call GetTimeZoneInformation(...) to get the difference between local
time and UTC (GMT)

or you can use CTime so you can get the difference

CTime time(CTime::GetCurrentTime());
tm t1 = *(time.GetLocalTm());
tm t2 = *(time.GetGmtTm());

TRACE("Difference between local time and GMT is %d hours.\n",
t1.tm_hour - t2.tm_hour);
