The files are created sequentially on-the-fly.  If you changed time on
the machine, then the timestamps in the file can be switched.  Look at
the last line of the log entries you submitted...did your machine
suddenly switch to daylight savings time at that point?

These are from the system crontab, /etc/crontab.  It has a job that
fires up every hour at 1 minute after the hour to run anything in
/etc/cron.hourly.  However, it starts the shell BEFORE it realizes
there's nothing in /etc/cron.hourly and that's what you're seeing--the
shell launch.  Note in your items below that the shell lasts for less
than a second.

If it's truly annoying, then edit /etc/crontab and comment out the

	01 * * * * root run-parts /etc/cron.hourly

line and it'll go away.
