Tzafrir, Gilad

It sounds to me like a case of a very sick realtime clock - maybe the motherboard is sensitive to voltage fluctuations - i think the clock might be a vco

Are you using ntpd? If not - I would try running ntpd and see if the problem goes away

Hi

I have a strange problem here: the system clock of my server keeps
changing.
The following is from the output of 'date' run from the same shell about
1 second apart:

  12:13:37
  13:25:08
  12:13:34

As you can see, the clock occasionally loops back (it keeps in the range
12:13:34-38) and occasionally decides to move about 72 minutes forward.


OK, this is getting kind of weird...

Just yesterday a client of mine asked me to help with a problem with an Asterisk installation running on Xorcom's Rapid (that is debian sarge + asterisk). The problem was that Asterisk seems to just exit for no apperant reason from time to time.

Going over the config and logs the only thing I found was that the system time seems to behave in a weird way, it seems that different program have different notion of the system time. e.g.:

# init q

and

# logger "test"

will produce syslog entries which are 4 hours apart...

Such behaviour can surely explain sidden program shutdown (at least a program that uses timers)

I have no idea if this is related, but it sure is strange to hear about a time drift related issue with sarge.

In short, I'd really like to hear if anyone has any idea how to resolve this too :-)
