This is adapted from HUD Real Time Clock by Craluminum. See https://mods.vintagestory.at/hudrealtimeclock for details and config options.

Note: The 'Format' option is removed so you are limited to a 24-hour clock of HH:mm but the rest of the options are active for location, color, font, etc. Also, the display may not start changing for some moments on entry. This is the game behavior, not the mod (check the 'C' display to confirm this). The show/hide is 'O' as it is for the original. If you try to use both, this may not work as intended. YMMV. I will release source at some point.

If you like this mod, support Dana, who is a one-person mod machine. Bugs are on me though.
