Time Zone Lookups

You can get a list of time zones nearest to a geographical location, optionally filtered by country. All of these functions return a list of ZoneDescription:

timeZonesByProximity(latitude, longitude);
timeZonesByProximity(latitude, longitude, country: 'US');

You can list all time zones in a specific country:

timeZonesForCountry('CA');

Or you can just list them all:

allTimeZones();
