Cliniko status:

Incorrect timestamp formats given on API responses

Incident Report for Cliniko

Resolved

For a brief time the Cliniko API was returning timestamps in a different format than usual. Instead of our standard format of "2025-05-27T17:44:48Z" we were instead sending "2025-05-27 17:44:48 UTC". The timestamps are still correct, but not in our standard format.

This problem began at 07:15 UTC on 8 Sep 2025 and the core problem was fixed at 07:30 UTC. But we may have continued to send the incorrect format in some places due to caching until 08:40 UTC. This affected all datetime timestamps given by the API.

If you persist data from our API, you may want to check for timestamps in that format and correct them.
