Returns the list of supported time zone identifiers for the Integration API. Use the returned Id values (for example W. Europe Standard Time) as the timezoneId attribute on the root element of Integration XML requests. If timezoneId is omitted, the system uses the default workspace time zone.

How to usw timezoneId

Default behavior (no timezoneId):

<Tasks projectId="...">
  <Task>
    <StartDate>15.09.2024</StartDate>
  </Task>
</Tasks>

Explicit time zone:

<Tasks projectId="..." timezoneId="W. Europe Standard Time">
  <Task>
    <StartDate>15.09.2024</StartDate>
  </Task>
</Tasks>
📘

Do not include offsets (for example +02:00) in date values. The API determines the correct offset automatically based on the provided date and workspace configuration.
