Hi Perderabo

Thanks a lot for the reply. I have few clarifications required and information to be given here ....

Quote:

First, I would manually adjust the clock to be closer. You're 900 seconds off assuming your 15 minutes is accurate. ntp maxes out at about 1000 seconds. Next, any errors in the logs? And check your ntp config: use a good server and use a drift file.

What exactly is the meaning that "ntp maxes out at about 1000 seconds" ?

There is no errors in the logs ... actually the logfile is not updated after NOV 2005. Thats really amazing.

Can you pls suggest a good server? My server is located in US California.

How to use a drift file? Whats the use of that?

Thanks a lot in advance

ntptrace

NTPTRACE(1)						      General Commands Manual						       NTPTRACE(1)

NAME

       ntptrace - trace a chain of NTP servers back to the primary source

SYNOPSIS

       ntptrace [ -n ] [ server ]

DESCRIPTION

       ntptrace determines where a given Network Time Protocol (NTP) server gets its time from, and follows the chain of NTP servers back to their
       master time source. If given no arguments, it starts with localhost. Here is an example of the output from ntptrace:

       % ntptrace
       localhost: stratum 4, offset 0.0019529, synch distance 0.144135
       server2ozo.com: stratum 2, offset 0.0124263, synch distance 0.115784
       usndh.edu: stratum 1, offset 0.0019298, synch distance 0.011993, refid 'WWVB'

       On each line, the fields are (left to right): the host name, the host stratum, the time offset between that host and  the  local  host  (as
       measured  by  ntptrace;	this  is  why  it  is not always zero for "localhost"), the host synchronization distance, and (only for stratum-1
       servers) the reference clock ID. All times are given in seconds. Note that the stratum is the server hop count to the primary source, while
       the synchronization distance is the estimated error relative to the primary source. These terms are precisely defined in RFC-1305.

OPTIONS

       -d     Turns on some debugging output.

       -n     Turns off the printing of host names; instead, host IP addresses are given. This may be useful if a nameserver is down.

       -r retries
	      Sets the number of retransmission attempts for each host (default = 5).

       -t timeout
	      Sets the retransmission timeout (in seconds) (default = 2).

       -v     Prints verbose information about the NTP servers.

BUGS

       This program makes no attempt to improve accuracy by doing multiple samples.
