The timezone on a Microsoft Windows system can be changed from the command line by opening a command prompt window with administrator privileges and then typing
timedate.cpl and
hitting Enter, which opens a window where you can alter the
timezone or you can use the
tzutil utility to
change the time zone using a command of the form tzutil /s
"TimeZone" where TimeZone is the appropriate time zone
identifier, e.g., tzutil /s "Eastern Standard Time".
