Thanks. I may resort to something like that, but there are a couple of problems. First is that my machine is almost never on at midnight. The second is that the time servers try to avoid being hit "on the hour" by everybody. I would have to find out how to set the time it is run offset by some arbitrary number of minutes. Since my machine is off as much as it is on, time updating at boot is a good choice. That way there is no chance that some random program will encounter a file with a future time. -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
