How to use Check time
- On the map page, enter two cities in the floating panel (e.g., London and Tokyo).
- We geocode both places and compute time differences from the IANA time zone database, including daylight savings when relevant.
- The glowing labels show current time and the hours ahead/behind.
- Share or bookmark the result — the URL contains your cities:
?a=London&b=Tokyo
