Computers will change their time at 2 a.m. local time. Consideration should be given to Scripts or CRON jobs that are scheduled to run during these early hours.
In the Spring the computer time will change from 2 a.m. to 3 a.m. Therefore any Scripts or CRON jobs that are scheduled to run between the hours of 2 to 3 a.m. will be skipped and should be temporarily changed to run at a different time (either before 2 or after 3) or manually run.
In the Fall the computer time will change from 2 a.m. back to 1 a.m. Therefore any Scripts or CRON jobs that are scheduled to run between the hours of 1 to 2 a.m. will run twice. If having the Script or CRON job run twice poses a problem then the scheduled time should be temporarily changed to run after 2 or before 1 or turned off and manually run at a different time.
