clock: Display home time zone as well as local zime zone

[joriscode]

Context When traveling, it is convenient to keep track on home time zone while also having local time zone available. My preference is to set automatically main clock on local time zone and have a secondary clock set manually on my home time zone. This allows me to be aligned with the place I'm at the moment while also being aware of home time for meeting and personal calls.

Suggestion Allow a second clock on main & lock screens.

• Clock app has a Home time zone settings with possibility to display it. Within the app, I can see my local time on top and home time beneath (and below other selected time zones). I imagine this information could be used by the launcher.
• To enable it, I think the settings from the Clock app could be re-used (if accessible) and additional parameters on the launcher appearance could be applied.
• About the layout, the simpler the better: a top left main clock and a smaller on the right home clock. I imagine format as time and date. Only main clock would be displayed if there is no time difference between the two clocks (and therefore, the usually display settings could be applied: position, format, ...).
• I would limit the functionality to main and local clocks, discarding the possibility to display custom time zone.

Thank you for considering this feature. I tried to give an idea of what it could look like and I'm aware this is a more complex feature that it sounds at first!
