possible different clocks

1. compare hwclock osclock/ntp TZ (read below)
2. compare dmesg with syslog (post more lines)
3. try: "halt", waitanyminutes, than boot
4. check disk badblocks

  -> timejump...

- cfg:
$ grep ^zone /etc/rtc_config
zone_info=Europe/Berlin
zone_lag=-3600

- The solution:
  Dom0's real time (hardware) clock has to be set to UTC!  [1]

## script fix TZ
yourtimeserver="changeit"
rtc
f=/etc/rtc_config
cp -p $f $f.old
rtc -z UTC
svcadm disable ntp; ntpdate $yourtimeserver; sleep 3;svcadm enable ntp;sleep 3
ntpq -p
