This response includes fields such as name, abbreviation, iana, and utcOffset. The name field indicates the name of the time zone, while the abbreviation provides a shorthand reference. The iana field specifies the IANA time zone identifier, and the utcOffset indicates the difference from UTC.

Another significant feature of the World Timezone API is the ability to retrieve time zone information based on a specific country or city. Developers can input the name of a country or city, such as "Germany" or "Berlin," and the API will return the corresponding time zone information.

{"result":{"placeName":"Germany","timeZone":{"time":"2023-03-28T21:51:17","utcOffsetWithDst":"2:00","name":"W. Europe Daylight Time","abbreviation":"CEST","iana":"Europe/Zurich"}}}

The response includes the placeName, which indicates the queried location, and the timeZone object, which contains fields such as time, utcOffsetWithDst, name, abbreviation, and iana. This feature is particularly useful for applications that need to display local times for events or social media posts across different time zones.

Timezone by Coordinates API Features

The Timezone by Coordinates API offers a straightforward feature that allows developers to retrieve the timezone based on geographic coordinates. By providing latitude and longitude values, developers can obtain the timezone information for that specific location.

{"dstOffset":0,"rawOffset":-28800,"timeZoneId":"America/Vancouver","timeZoneName":"Pacific Standard Time"}

The response includes fields such as dstOffset, which indicates the offset during Daylight Saving Time, rawOffset, which shows the standard UTC offset, timeZoneId, which provides the IANA time zone identifier, and timeZoneName, which gives the common name of the time zone. This feature is particularly useful for applications that need to display local times based on user location or for services that require accurate timekeeping based on geographic data.
