Adjusting Report schedules for DST changes

Products

• Clarity PPM On Premise

Issue/Introduction

If your server recognizes Daylight Savings Time (DST), you may notice the report jobs scheduled using simple recurrence delayed by one hour (when DST ends) or runs an hour earlier (when Daylight Savings Time (DST) begins). Day light time changes can impact the Jaspersoft (Advanced Reporting) report schedules.

Environment

Release: All

Resolution

If you want jobs to recur at the same time of day and respect DST adjustments, use calendar recurrence instead of simple recurrence.  Calendar recurrence options are:

1. Months – The months during which the report runs.
2. Days – The days when the report runs:
   • Every Day
   • Week Days
   • Month Days – Enter dates or date ranges separated by commas, for example: 1, 15.
3. Times – The time of day in minutes and hours when the job should run. The hours use 24-hour format.

You can also enter multiple minutes or hours, and ranges, separated by commas. For example, entering 0, 15, 30, 45 for the minutes, and 9-17 for the hours, runs the report every 15 minutes from 9:00 a.m. to 5:45 p.m. Enter an asterisk (*) to run the job every minute or every hour.

     4. Recur Until – Calendar Recurrence runs until a calendar date is reached. Click  to select the date.

Notes:

• If you need to use an interval that is not available in Calendar Recurrence, see Schedule Reports in 3 week intervals while avoiding DST Issue

• When the start date for a job has passed, it is ideal to stop the existing job by deleting and start a new job rather than changing the start date of the existing job.
