Subject: [ilugd] Time Lag in Linux...


Hi all,

I am using RH linux 7.2 (kernel version 2.4.7-10). I am facing a problem
with time drift w.r.to real time.

Let me explaing this in detail
--

I set time using date command and then /sbin/clock -w to set
the RTC time as system time. I also run /sbin/clock -s to sync
system time with RTC using cron for every 1 hour.


RTC(cmos) SystemTime(linux)  Real Time(accurate digital watch)

11/08/2003  10:10:10 10:10:10   10:10:10
18/08/2003  10:10:24 10:10:24   10:10:10

After 7 days (system is continuously running), i find the difference
14 seconds over the real time.

This time lag cannot be accepted in if we have to use real time
applications which depends heavily on time.


Can someone tell me why there is a time lag...
If it cannot be compensated... is there a way to synchronize RTC/system time
with real timein Linux...!!!

I shall appreciate any help in this regard...
