init is a little screwed up. For some
reason, after a shutdown record is written, a reboot record is
written with a time-stamp before the shutdown (less than
30 seconds, usually).
TANGIBLE RESULT: GNU
notice the problem, log everyone out (you can specify if you want
the time to be added to the user's total) and begin a new day
entry based on the time of the out-of-sync record. If you try to
print out daily totals, you'll notice that some days might have
two or more entries.
SOLUTION: To fix this, a timewarp leniency value has been implemented. If any record is out of order by this number of seconds (defaults to 60) it gets ignored. If you need to change this value (if you think the totals are off because the value is too high), you can change it using the `--timewarp-value' flag. The rationale for the 60 second default is that of all of the machines with this problem, the largest timewarp was 45.
