I've heard that using a simple "ntp -s" or "ntp -f" isn't good for the system because the clock might jump to the correct time from whatever it was set at before and cause a crontab entry to be skipped. I don't know if this is true and, therefore, was wondering if it would be a good idea to stick an "ntp -s <ntp host>" in as a crontab entry running every 10 minutes? I figure the worst that will happen with this is that the clock will be set correctly the first time and never be too far off from what time it *really* is. Unfortunately, if my clock isn't that good, it will only be correct on the 10th minute, when it was jerked to the correct time. If there is a way to ease the clock forward or backward (accelerate or decelerate the ticking of seconds, I suppose) so that the clock was correct relatively all the time and not pass up any minutes or seconds (thus solving any problem with crontab entries being skipped), how is that done? Thanks. -- -- Jeff (jeffo@uiuc.edu) -- no NeXTmail please
