World clocks in the title bar

It would be great to show one or more world clocks in the title bar, next to the local time.

Use case: I have friends, family and colleagues in other time zones, and I travel a lot. A quick look at the desk display to see what time it is in e.g. Shanghai or Bangkok would be very handy, without opening an extra page.

Ideas for how it could work:

Configure 1–3 extra clocks per screen, each with a time zone (IANA, e.g. Asia/Shanghai) and a short label (e.g. "SHA" or "Shanghai") Compact display like SHA 18:42, optionally with a day offset (+1) when the date differs Option to switch between showing all clocks at once or cycling through them every few seconds if space is tight 12h/24h format following the main clock setting Optional: a small day/night indicator (e.g. sun/moon icon) per clock

Thanks for the great project!
