Savings Time on cron(8). If we ever introduce some work-around code for
handling jobs scheduled for a time that "doesn't happen" due to DST,
the section should be renamed to IMPLEMENTATION NOTES.

If you're in one of the 70-odd countries that observe Daylight
Savings Time, jobs scheduled during the rollback or advance will be
affected. In general, it's not a good idea to schedule jobs during
this period.

For US timezones (except parts of IN, AZ, and HI) the time shift occurs at
2AM local time. For others, the output of the
.Xr zdump 8
program's verbose
.Fl ( v )
option can be used to determine the moment of time shift.
