Bug 687946

Description of problem:
I hope I'm reporting this to the right place - 
 cat /etc/issue =>
 CentOS release 5.4 (Final) ...
I've not done any yum update for a long time, so this might be a fixed
bug, but I don't see it in the list.

Here's the file /root/monitor-load
====
uptime >> /tmp/load-record 
at -f /root/monitor-load now + 5 minutes 2> /dev/null 
====
I start it by putting the second line into a shell.
The output file, /tmp/load-record, includes this:
... one record every 5 minutes until just before the switch to daylight savings time

 01:53:00 up 424 days, 19:24,  1 user,  load average: 0.00, 0.00, 0.00

 01:58:00 up 424 days, 19:29,  1 user,  load average: 0.00, 0.00, 0.00 
and now we seem to be running the job as soon as possible until
 01:59:59 up 424 days, 19:31,  1 user,  load average: 2.23, 0.84, 0.30 
 01:59:59 up 424 days, 19:31,  1 user,  load average: 2.23, 0.84, 0.30 
 01:59:59 up 424 days, 19:31,  1 user,  load average: 2.23, 0.84, 0.30 
 03:00:00 up 424 days, 19:31,  1 user,  load average: 2.23, 0.84, 0.30 
 03:05:00 up 424 days, 19:36,  1 user,  load average: 0.01, 0.30, 0.21 
 03:10:00 up 424 days, 19:41,  1 user,  load average: 0.00, 0.10, 0.14 

I suspect that at 1:58, now + 5 minutes is interpreted as 2:03 and that
in turn is somehow viewed as 1:03, which means run it immediately.
