How the World Clock works
When you load the clock it fetches the current time once from our server, so it stays accurate even if your device clock is slightly off. It then ticks forward locally each second and formats the time for each city using that city's IANA time zone, including any daylight saving time currently in effect.
To convert a specific future time between zones, for example to schedule a meeting, use the Time Zone Converter.
