Many countries also have Daylight Saving Time (DST) for part of the year, the time service will automatically switch to this at the appropriate time unless DST has been disabled.
For example 'Eastern Standard Time' represents both EST (UTC-05:00) and EDT (UTC-04:00)
The Microsoft Deployment Toolkit (MDT) will use these values in a scripted install, e.g.
TimeZone=004
TimeZoneName=Pacific Standard Time
The time zone names above are Microsoft terms which do not always match the official ISO name of the Time Zone,
in particular 'GMT Standard Time' should not be confused with 'Greenwich Mean Time' (GMT)
Greenwich Mean Time implies no apply daylight saving.
