Problem definition

When timestamp values (e.g Worklog) are retrieved through REST API the values will be based on the timezone of JIRA instance. REST API response does not contains the timezone offset or any clarification about the timestamp value retrieved. This could cause a lot of pains to understand which timezone the data is based on.

Suggested resolution

Please update REST API documentation and add the clarification about timezone for endpoints that returns a timestamp value. For example, add the information about the timezone data (timestamp) is based on, and how to get the timezone.
