In a prior post I outlined a method to set the time zone from the command line using a control panel applet. I needed to do this to fix a problem with the Mac RDP client which doesn't work correctly with time zone redirection. Using the control panel applet works great on XP and 2003 Server, but only launches the Date and Time applet on 2008 and Windows 7. After a little bit of research, I found a utility called tzutil that's included with Windows Server 2008 and Windows 7. This is the same utility Microsoft used to change time zones during the last daylight savings time calendar change. [more]
Syntax: tzutil /s "Central Standard Time"
