Schedules and Daylight Saving Time

A schedule programmed to start during the Daylight Saving Time (DST) change interval will not operate normally.

At the start of the DST period, when clocks are adjusted forward from 2:00 to 3:00 AM, schedules programmed to start between 2:00 and 2:59 AM inclusively will not start. Furthermore, weekly and monthly schedules programmed to start between 2:00 and 2:59 AM inclusively on any day during the following week will also not start.

Example: On Sunday, March 9, 2014, the clock of a Coveo server running in the USA is adjusted forward at 2:00 AM. A CES weekly schedule programmed to start on Friday, March 14 at 2:15 AM does not start because it occurs within one week following the DST forward adjustment.

At the end of the DST period, when clocks are adjusted backward from 3:00 to 2:00 AM, schedules programmed to start between 2:00 and 2:59 AM will start twice.

To prevent these issues, it is therefore recommended to avoid programming a schedule to start during the DST clock adjustment time interval (typically between 2:00 and 2:59 AM).
