Detailed Description and Symptoms

?Whenever Daylight Saving Time changes happen, there are many questions regarding how Automic handles the change and if there are any known issues  that might arise during or after the change. There is information in the Automic documentation regarding how Automic reacts to time changes from Daylight Saving Time to Standard Time which can be found under Inside Automic Guide, Date and Time, Changing from Normal Timeto Daylight Savings Time.


There have been issues in the past with the Daylight Saving Time change, but as far as Automic is aware, all of these have been fixed. Please see the information below regarding these issues. These can also be found at downloads.Automic.com by choosing the corresponding Application and Version (Automic Automation Engine for 9.OOA and Automic Operations Manager for 6.OOA and 8.OOA).

 


Solution

Automic Automation Engine (9.00A)
Fixed in 9.00A Service Pack 1 (AutomationEngine hotfix 117-821)

 

 
29.06.2011 | 9.00A SP 1 DST changeover to standard time causes erroneous start time for recurring objects.
Error description:
Changing the daylight savings time over to standard time (winter time - the clock is set back for one hour), the system does not change the next scheduled start time of recurring tasks. As a result, no recurring tasks start for a period of one hour. The tasks are executed in the specified interval only when when the old start time is reached or exceeded.
 
For example:
The object SCRI.TEST starts on 31.10.10 at 2:20 (recurringly, every 10 minutes).
 

 

At 3:00 o'clock, the clock is set back for one hour (to 2:00). The next scheduled start time, however, remains 3:00. Therefore, the system does not start tasks between 2 and 3 o'clock.
