Hi Timekit Travellers,

Officially supported Timezones are constantly changing. As a result, some timezones that used to be supported in Timekit may fail to work as we update to the newest standards.

If you send a request using a no-longer supported timezone, Timekit will respond with:

{

"errors": {

"customer.timezone": ["The customer.timezone must be a valid zone."]

}

}

when a booking is created via the /v2/bookings endpoint.

Some examples of no-longer supported timezones include

  • "timezone":"America/Montreal"

  • "timezone":"Etc/GMT"

  • "timezone": "US/Pacific"

  • "timezone":"US/Mountain"

  • "timezone": "Asia/Calcutta"

As an alternative to the above, you can use:

  • "timezone":"America/Montreal" -> "timezone":"America/New_York"

  • "timezone":"Etc/GMT" -> "timezone":"Africa/Abidjan"

  • "timezone": "US/Pacific" -> "timezone": "America/Los_Angeles"

  • "timezone":"US/Mountain" -> "timezone":"America/Denver"

  • "timezone": "Asia/Calcutta" -> "timezone": "Asia/Kolkata"

The entire list of supported timezones we use is the timezone database 2021.5 https://github.com/tzinfo/tzinfo-data/releases which is also listed here https://www.php.net/manual/en/timezones.php
