Oozie TimeZone handling for Daylight saving (CRON Expressions)
I have a Oozie application that suppose to respect Daylight savings. However my schedules are complex so I can't represent them as Expression Language functions such as ${coord:days(2)} . Therefore I need to use CRON expressions.
One example of schedule is every week on weekdays at 13:30 PM (resulting cron expression for Oozie "30 13 * * 2-6" with no time zone adjustment) America/Los Angeles timezone. I want this schedule to works fine regardless of the DST changes.
If I schedule this workflow on some time between Nov 6th & March 13th time zone adjustment is 8 hours. However it's 7 hours outside this period. So if I schedule it with "30 21 * * 2-6" and set my coordinator application timezone to "America/Los Angeles" would my app running on correct schedule even with day light saving adjustments? or do I need to adjust it so 7 hours? Any solution to this problem really appreciated.
Note-1: Oozie processing time is UTC. Note-2: I have use cases where I need to do it for different time zones. So PST was just an example.
Sample Coordinator App definition below
