I've set up a nightly cron job to run ntpdate, and so every night I receive dandy cron output by mail. I've set my securelevel to 3, so it'll clamp any time adjustments to 1 second max. After a week or so of running this setup, I noticed a pattern. This output was on a box with a 3-day uptime: 27 Jan 03:00:05 ntpdate[58255]: step time server 62.4.94.211 offset 11.482178 sec You may notice that the offset, having been corrected two times before, is almost 12 and as such 3 * 4. And that's exactly what's been going on: every night, the clock skew equals a four-some seconds. So what I'm wondering is: is this due to an erred clock calibration or is my E250 clock timer hosed?
