[ntp:questions] OT: Linux and NTP

Hello Group,

I've setup two NTP servers for the network. These two servers
synchronize time with two public NTP servers. The other computers
synchronize time with my NTP servers. Everything works fine but my two
NTP servers have different times (21 seconds difference).

Server 1:
# /sbin/hwclock ; date
Mit 26 Nov 2003 18:16:52 CET  -0.560965 Sekunden
Mit Nov 26 18:16:30 CET 2003
# /usr/sbin/ntpq -p
     remote           refid      st t when poll reach   delay   offset
 jitter
==============================================================================
 LOCAL(0)        LOCAL(0)        10 l   23   64  377    0.000    0.000
  0.015
+chronos.zedat.f .GPS.            1 u  227  512  377   15.887  -74.098

*ntp0-rz.rrze.un .GPS.            1 u  168  512  377   25.028  -70.056

Server 2:
# /sbin/hwclock ; date
Mit 26 Nov 2003 18:16:51 CET  0.333037 Sekunden
Mit Nov 26 18:16:51 CET 2003
# /usr/sbin/ntpq -p
     remote           refid      st t when poll reach   delay   offset

==============================================================================
 LOCAL(0)        LOCAL(0)        10 l   43   64  377    0.000    0.000
  0.000
*chronos.zedat.f .GPS.            1 u   44   64  277   17.101  -70.165
  2.183
+ntp0-rz.rrze.un .GPS.            1 u   62   64  377   25.312  -60.754
  2.702

It seems that hardware time is correct but NTP uses software time,
doesn't it? If I fetch the time manually with ntpdate on both servers,
there is also a time difference of 21 seconds.
Any ideas? Thanks in advance.
