So I'm trying to build a batch file that will either automatically toggle between 2 time zones; or take a user input and change the time zone accordingly

I tried to have a toggle system but I can't figure out how to store the current time zone based on tzutil /g or setup if statements correctly to identify which time zone to change to. I run it in admin mode so thats not the issue.

@echo off
echo The current time is:
tzutil /g
echo.
SET /p NewTimeZone="Enter the time zone you wish to change to: "
tzutil /s %NewTimeZone%

the first part works fine, it tell the user what time zone it's in and then asks to change it. however that last line is whats causing all the trouble, I can't seem to get it work, for example when I run the code, I type in: "Mountain Standard Time" which is the string its needs to change the time however it never goes through, it just closes the program and the time zone never changes

    Have you tried putting quotes around the variable: `tzutil /s "%NewTimeZone%"` – HAL9256 Jun 10 '19 at 21:46
  • TBF, it's not uncommon for people not to expect, `Set /P Var="Prompt"` to actually replace, `Prompt` with `Input`. The recommended syntax is `Set /P "Var=Prompt"`, which may help you better see it better. – Compo Jun 10 '19 at 22:03

  • for the "troubleshooting" part: don't run per double click, open a `cmd` window and execute the script from there. It can also be very useful to run it with `echo off` – Stephan Jun 24 '22 at 18:14

Usually you get a command's output with a for /f loop:

for /f "delims=" %%a in ('tzutil /g') do set "org=%%a"
echo original=%org%

You can also put it into a file (so it survives even a reboot):

>original.zone tzutil /g
type original.zone

and get it back with:

<original.zone set /p "org="
echo original=%org%

and set it back (with both methods):

tzutil /s "%org%"

You can verify the user's input like:

set /p "new=Enter new time zone: "
tzutil /l | findstr /ix "%new%"
if errorlevel 1 ( echo non-existing zone & goto :eof )
tzutil /s "%new%"

You need to use:

tzutil /s "%NewTimeZone%"

In last line
