Changing the time zone on a Microsoft Windows system from the command line

Learning that lasts. Online courses from $14.99

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".

The list of time zones can be found in the Windows Registry at Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones — you can view the list with the registry editor regedit.exe and then navigating to that registry key.

Registry Time Zones

If you navigate to the one that is applicable you will see the keys displayed below.

Registry Time Zones - EST

You can also view the list of time zones from a command prompt using reg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Time Zones" /s to view all of the subkeys of the Time Zones key in the registry. That will produce a lot more information than you need - see regquery_timezones.txt, but you can restrict the output displayed to just the time zone names by piping the output of the command to the findstr command. E.g.:

The /R option for the findstr command indicates that you want to find a string based on a regular expression you will provide (see findstr parameters). In this case, I want to find lines that have Std in the line where the Std is at the beginning of a word, so I don't inlcude the lines that contain MUI_Std — the backslash before the less than sign is an escape character that "escapes" the meaning of that sign.

If you you want to see how a time zone difers from Coordinated Universal Time, you can view the "Display" value, which can be obtained using the command below.

E.g., Eastern Standard Time is Coordinated Universal Time (UTC) minus 5 hours.

An easy way to view and set time zones from a command prompt is to use the time zone utility tzutil. To view the current time zone, you can use tzutil /g. To see the list of time zones, you can use tzutil /l. You can reset a time zone using tzutil /s "Time Zone ID", e.g., tzutil /s "Eastern Standard Time".
