This information has already been removed from the log file.  It only
stores about 3000 minutes worth of 5-minute samples (2 days + 2 hours).

The data is still available in the 30-minute samples, and should be
visible in the weekly log.  If necessary, turn on "WithPeaks".

If you have backups of your logfiles, you could restore them and perhaps
reset the time on you machine (cron disabled; restore in another dir).

See the doc directory for more information on the logfile format.

Suggestion for future problems:  Each midnight move the *-day.gif file
to *-yyyymmdd.gif (i.e. move router-day.gif to router-20000103.gif).
Use yyyymmdd to autosort the files.
