Uses the UTC vs. local timezone code from the original project by 2okrisvadh. Other code is by me. Image is from https://www.1blueplanet.com/world_time_zones/webp/TIME_ZONE_16_NO_100_10.webp v1: Original release. v1.1: Removed a redundant sprite. Added a show/hide map button. v1.2: Fixed initialization bug that caused the overlays to be hidden if you showed the map and pressed the stop sign. v1.3: Fixed a bug where the clock would display incorrectly if the hour was a one-digit number.
