how do i change timezone using adb

Question

I want to change the timezone using adb shell command.

I went through some posts which allow changing it in linux, but they are not valid for android.

Answer 1

adb shell service call alarm 3 s16 America/Phoenix, which will be effective immediately.

"setprop with persist.sys.timezone" only works after reboot.

Answer 2

For the list of tzdata values I go to http://en.wikipedia.org/wiki/List_of_tz_database_time_zones

To set the timezone use setprop persist.sys.timezone <TZ> command:

setprop persist.sys.timezone "America/Chicago"
