Q:

Change timezone of browser

I need to run browser with a timezone other than operating system's time zone. Is there any way to customize time zone in any browser or is there any plugin available that provides such functionality?

A:

If you are on Linux, you can launch a process while setting an environment variable for the lifetime of the process. Linux uses the environment variable TZ for time zone configuration. For example, the following command will run firefox using UTC timezone.
TZ=UTC firefox
