Watches are perfectly acceptable time keepers especially considering I have a cheap watch stuffed in a drawer that I was surprised hasn't lost seconds in years. RTC: I'm fairly sure many older ones don't even have crystals but are probably still good enough, though I have no accurate quantification yet. > Like everything else ntpd has to be properly secured and configured, if > properly done I suppose it isn't a bigger security problem than anything > else with network access.

Attacker controlled or influenced time is actually more serious than you would think for crypto, logging etc., which is why OpenBSD put so much effort into it and don't allow the clock to go backwards. So do the benefits of ntp outweigh the risk. I'm simply saying in most scenarios no. I'm not saying ntp is at fault, however manually setting the date fixes this problem. So the easiest and in my opinion best solution for most users that wasn't put forward for most users is to disable ntp and set the clock to mr atomic. -- ________________________________________________________ Why not do something good every day and install BOINC. ________________________________________________________
