Frequently asked questions
How many cities can I add?
As many as you like. Add several World Time blocks, or several cities within one, depending on how you want them laid out.
Does it handle daylight saving time?
Yes. Times come from your system time zone database, so daylight saving shifts are applied automatically.
Does the world clock work offline?
Yes. Time zone conversion is computed locally, so it keeps working without a connection.
