Roaming time zone

Again, I’m pretty sure I already know the answer to this but I’ll ask anyway.

Is there any way to know, from Tags in WFS, that you have left your ‘home’ timezone, and what is the time difference between the current timezone and your home timezone?

Has anyone developed a watchface in Android Studio which can do this?

The tag [TMZN_OFS] may be able to work but it looks like it returns a string and not a number and while it says for UTC it doesn’t show the DST offset for my site.
