No. Internally, all 32-bit Windows (from Windows NT in 1992 and Windows 95 in 1995) keep time internally in UTC, and have the option via the regional settings to display time in "local time". The local time offset can change between summer and winter as you wish. All this is already built into Windows. The internal timekeeping does not change when a time-zone is specified, just the time displayed to the user. Much of my software, for example, which deals with satellite tracking, uses UTC throughout, and obtains this via a single system call to Windows: GetSystemTime http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/getsystemtime.asp Windows assumes that the RTC on the motherboard is set to local time, as it would typically be set from someone's watch when it is first set up by an individual user (it may be set to Chinese or Taiwanese time when first delivered).
