>Organization:

>Environment:

2.2.7-STABLE, also 3.1-RELEASE

>Description:

Daylight time (at least in the US) begins at 2am.  By default, /etc/daily runs
at 2am, so when the clock changes from 01:59 to 03:00, any cron jobs set to 
run at the 2am hour will get skipped.  Every n minute jobs get skipped also, 
but that isn't as bad as having something that specifically runs at the 2am
hour getting lost.

I wonder how cron acts when we get the hour back in the fall.

>How-To-Repeat:

Install FreeBSD 2.2.7 or 3.1, wait for daylight time to begin, and see that
/etc/daily or anything else that you have running between 02:00 and 02:59
on that day will not run.

>Fix:
	
Do not run things at 2am, and include a little note in the crontab file about
this.  It may not be a good idea to have cron go and rerun 02:00 to 02:59 
missed jobs.
