Fixed Issue with OFBiz Job Scheduler and Daylight Saving Time (OFBIZ-12864)
(#674)
* Fixed recurring job not scheduling when DST change
The issue occurs when DST changes, and OFBiz fails to schedule recurring jobs
properly. This is due to a condition in the
PersistedServiceJob.createRecurrence method where it compares the next
scheduled time (next) with the start time (startTime) for the job.
To address the issue, adding a new field named JobSandbox.runTimeEpoch.
This field would store the UTC format epoch milliseconds of the runtime date.
When scheduling or rescheduling recurring jobs, the system would use the UTC
epoch stored in JobSandbox.runTimeEpoch for comparison.
This solution ensures that the system uses a consistent, UTC-based time for
scheduling and rescheduling recurring jobs, even when DST changes affect the
local time.
To implement this solution, you would need to:
Modify the PersistedServiceJob.createRecurrence method to calculate and store
the UTC epoch milliseconds in the JobSandbox.runTimeEpoch field.
Update the code responsible for polling and rescheduling jobs to use the
JobSandbox.runTimeEpoch field when it is set. If the field is not set, you
would fall back to getting the runtime date to filter the jobs.
By using this approach, system should be able to handle recurring job
scheduling more reliably, especially when DST changes are involved, as it
ensures that all time comparisons are made in a consistent UTC format.
* Checkstyle fixes
* Store the runTimeEpoch while recurring job scheduling
