timezone-data

This package contains a list of time zones from release 2022b of the IANA tz database.

Data extracted from https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

Note: in order to reduce package size there are some fields that if they don't have a value or they value can be infered from other field they are not included in the JSON list.

The fields in the array are as follows:

• tz: contains the time zone code. Always present.
• label: Only present in no deprecated time zones. Time zone Friendly name that can be shown to the user.
• offsetSTD: contains the offset from UTC for Standard Time. Always present.
• offsetDST: contains the offset from UTC for Daylight Saving Time. Only present if there is a Daylight Saving Time for that time zone, otherwise you can asume its value it's the same as offsetSTD.
• tzNameSTD: contains the time zone name for Standard Time. Always present.
• tzNameDST: constains the time zone name for Daylight Saving Time. If it doesn't have Daylight Saving time this field is not returned and you can safely asume it's the same as tzNameSTD.
• linkTo: constains the updated time zone code in case that the tz is deprecated. This field is only present if the tz is deprecated.
