[gentoo-user] System Clock Problems

[Drew Tomlinson]

I have Gentoo 2.6.13-r5 kernel running and have used ntpd in 
broadcastclient mode to keep its time in sync on my home network.  The 
other day, the system suffered and abrupt shutdown due to a power 
outage.  Ever since then, the system clock gains about 10 seconds every 
5 minutes.  Also, I can't get ntpd to sync the clock.  My command line 
is "ntpd -A -b -g -u ntp:ntp".  I've included some output running the 
command with the debug switch below.

I've also tried to gain more info with the ntpdc utility although I 
don't really know what I'm doing.  However it appears that ntpd does see 
my FreeBSD time server even though it's not synced:

ntpdc> peers
     remote           local      st poll reach  delay   offset    disp
=======================================================================
=192.168.1.2     0.0.0.0          2   64    7 0.00038 -9.600170 1.98438

The time server is a FreeBSD 6.0 box on my network.  My other FreeBSD 
box and two Windows boxes get time from it just fine.  Even the Gentoo 
box will set its clock with "ntpd -gq".  I am currently using this brute 
force method via a cron job as a temporary workaround.

Any ideas on what might have caused this recent change in behavior?

Thanks for your help,

Drew
