JSI Tip 1280. How do I check the time zone of a remote computer?

In tip 0398, we described the time zone information in the registry.

Using tip 0170, you can download the REG freeware.

To check the time zone on a remote (or local) computer, type:

JSITZ <ComputerName> \[/n\]

NOTE: You can also use JSITZ \\<ComputerName> \[/n\]

Example: To check the time zone on remote computer JSI002:


This returns a TZ environment variable. JSI002 is located in Alpharetta, Georgia - USA,
so TZ is set to "Eastern Standard Time".

If the <ComputerName> is not found, as in JSITZ XYZ,
TZ is set to "key \\XYZ\MACHINE\System\CurrentControlSet\Control\TimeZoneInformation"

NOTE: The optional /n switch suppresses the display.

NOTE: To check the time zone on your local computer, you can use JSITZ %ComputerName%

JSITZ.bat contains:

@echo off
set machine=%1
set machine=%machine:"=%
set machine=%machine:\=%
for /f "Tokens=1*" %%i in ('reg -lv "\\%machine%\MACHINE\System\CurrentControlSet\Control\TimeZoneInformation\StandardName"') do set TZ="%%j"
if /i not "%2"=="/n" @echo %TZ%
endlocal&set TZ=%TZ%
