| Summary | 0001033: CronResource with switch to daylight time causes multiple runs | ||||||||
| Description |
With CronResource, if there is a job scheduled to run during the 'missing' hour of a transition to daylight time, the job will be run over and over in the preceding hour until the daylight time transition. We have a CronResource configured to run daily at 2:15 AM. When CronResource runs (or is initialized), it calculates the time of the next run. When it ran 1 Apr 2006 it calculated the time of the next run as 2:15 AM on 2 Apr 2006. Our time zone is America/New_York, so daylight time starts at 2:00 AM on 2 Apr 2006, jumping to 3:00 AM. The local time 2:15 AM 2 Apr 2006 doesn't really exist, so the run time became 1:15 AM 2 Apr 2006, and that's OK. However, when CronResource ran at 1:15 AM 2 Apr 2006, it calculated the next run time as 2:15 AM on 2 Apr 2006 again, corrected that to 1:15 AM 2 Apr 2006 again, and ran again, over and over, until the the daylight time switch at 2/3 AM. A job that was configured to run once at 2:15 AM ran over and over from 1:15 AM until 2:00 AM. |
