Windows - 2 time zones, how to display?

Question

Monitors

It is necessary that
- either 2 time zones are displayed in the taskbar,
- or different time zones on two monitors,
- or some kind of plug-in for ms edge, so that the time is displayed there, different from the time of the operating system.
How to implement?

Answer 1

1st Clock allows you to show different time zones in the Taskbar.
For example, I threw the second one (don't pay attention to the format, they are configured, I just didn't set up the second test time zone):

Paid. You can probably look for a free analogue.
