Yes. PC-class hardware is notoriously bad and system times will vary by seconds or minutes within a few days.
I don't need microsecond resolution yet. I already said that my clocks are accurate.
Well sorry to say but you are fooling yourself very heavily there , If the acuracy with which the PC clock system keeps time the the world must be so far out of Sync it is untrue when you have a 09:00 appointment what time do you leave 12:00 the pervious day , PC clocks are pretty pi** poor to put it mildly
No, you are wrong. The PC system clock is quite correct and stable. It drifts, yes, but the drift is usually constant and can be accounted for in the kernel. This is a known fact and published, I think in the ntp docs. It is based in a quartz xtal, after all... random errors can come from missed interrupts, and there are not that many (and I believe modern hardware can make for those missed timer interrupts by looking at other internal timers). Even ntpd is not continuously touching the clock. It looks, it may adjust the drift a bit, and then may not look again for another hour. - -- Cheers, Carlos E.
