NOTE: Names and commands longer than their column width are truncated with an ellipsis. To
assist administrators in diagnosing problems with jobs, there is a detail view for a single job. If
the last job run produced any output, the first 255 characters of that output will be shown from the
last job run whether that job was successful or not. A successful run will overwrite the error output
from a previous failed run.
Time Adjustments
Daylight Savings Time Adjustments
When daylight savings time (DST) begins (“spring forward”), the local time jumps from 0200 to
0300. The Job Scheduler “catches up” by running all jobs scheduled between 0200 and 0300
the next time it wakes up. This prevents jobs from being skipped when they appear in the 0200
to 0300 time frame.
When daylight savings time (DST) ends (“fall back”), the local time jumps from 0200 to 0100.
The Job Scheduler skips all jobs scheduled between 0100 and 0200 to allow local time to catch
up. Those jobs already ran once before DST ended will not repeat.
NOTE: If an administrator configures a new job during the repeat of the 0100 to 0200 hour on
the day DST ends, the new job will not be run because the Job Scheduler skips that hour.
External Adjustments
External adjustments to the system time can happen to correct for clock drift or for other
administrative reasons. The new time update can come from SNTP, from a configuration command
at the CLI, or from an SNMP SET of the system time MIB object. When a time adjustment takes
place, the Job Scheduler task is called with the new clock value. Jobs scheduled during a time
clock jump forward are run while any jobs scheduled during a time clock jump back are skipped.
