We have written a custom implementation of OOB AbsoluteTimeAutoAdvancer workflow class. We try to schedule the workflow to trigger at a particular time (UTC time).
The code is working fine in various timezones, but for JST timezone, it seems to add random delays - 10 mins, 17 mins, 26 mins etc.
Because there is no consistent time duration, we are not able to identify what could be causing these delays.
We set a schedule time in UTC as metadataMap property and in AutoAdvancer implementation
Do we have any configuration which is causing delay in particular timezone. Please help.
Did you setup a new scheduler service in AEM here?
You may validate your implementation against this sample code to iron out any issues -

On click event there is sling servlet which will trigger the workflow. In workflow participant step Timeout is "Immediate" and Timeout handler we customised it by extending AbsoluteTimeAutoAdvancer class.
