1404484 - Scheduled instances' runtime adjusted by +/- 1 hour following DST time change (Linux / Unix)


  • In a Unix or Linux BI Platform environment, running on a server with different DST rules than those in the United States...
    • (different start / end date, or a locale with no DST)
  • Following the beginning or end of Daylight Saving Time -- in either the server's locale or the US -- scheduled instances' runtimes are adjusted by +/- one hour.
    • Recurring instances' next run times are (generally) updated to reflect the new scheduled start time, +/- one hour from their previous values.
    • Less commonly, the instances run an hour earlier or later despite their listed start times being unchanged
  • As an example, in an affected BI environment in Europe -- where DST ends on 29 October, 2023 -- instances will run one hour early after that date.*
  • The issue can typically be detected even before DST starts or ends, as recurring instances next run times begin to fall on dates that follow the DST change.
    • e.g. Where DST ends on 29 October, 2023, a weekly (Wednesdays @ 12pm) report will run at the correct time on Wednesday, 25 October, immediately after which the next run time is given as 1 November @ 11am.
    • *The same logic can be used to confirm if and when the issue will self-correct.  After the example instance runs on 1 November @ 11am, its next run time should be given as 8 November @ 12pm, confirming the issue will self-correct.
