but what I'm saying is that every second will still hit. It's just that
that second will only last for 0.8s. So to the code above the OS and even
the shell level system calls, there is no difference. The difference is
very lo level - interrupts come in every micro-second or so from the CPU

I believe K is asking whether he can sync up the clock now because he's
concerned about losing data, as 30-40 seconds is pretty bad.

NTP gradually speeds or slows the clock to arrive at actual time. So the
clock still hits every second but 1s may really be 0.8s or 1.2s. In your
case, it will sync up within a day. NTP is very clever so you never have
newer files back-dated to be older than older files or vice versa.

If you don't want to get ntp working there, why not just... manually... set
the clocks?

the clock is about 30 to 40 seconds behind.

How far out of sync are the nodes? A few minutes or less? Many hours?
Worst case, you could simply take the entire

Hi,
I have question about ntpd. In certain clusters where new datacenters were
added since 1 week we stood-up those machines didn't have ntpd running on them.
Will it cause any problem if we enable or start ntpd now on those newly added
datacenters.
Thanks.
