С сегодняшнего утра один из DC на моем рабочем месте изменил время на 2 часа позже, и я не могу понять, почему

Сервер получает обновления NTP с сервера Linux в среде:

C:\Windows\system32>w32tm /config /update
The command completed successfully.

C:\Windows\system32>w32tm /query /status
Leap Indicator: 0(no warning)
Stratum: 3 (secondary reference - syncd by (S)NTP)
Precision: -6 (15.625ms per tick)
Root Delay: 0.0371704s
Root Dispersion: 7.7930820s
ReferenceId: 0x5250CC1A (source IP:  x.x.x.x)
Last Successful Sync Time: 1/8/2013 6:43:24 PM
Source: srvname.out.DOMAIN.com
Poll Interval: 6 (64s)
C:\Windows\system32>

Это сервер Linux NTP:

[root@srvname ~]# hostname
srvname.out.DOMAIN.com
[root@srvname ~]# ntptime
ntp_gettime() returns code 0 (OK)
  time d496a4ae.61119000  Tue, Jan  8 2013 *15:59*:10.379, (.379174),
  maximum error 84347 us, estimated error 0 us
ntp_adjtime() returns code 0 (OK)
  modes 0x0 (),
  offset 0.000 us, frequency 5.091 ppm, interval 1 s,
  maximum error 84347 us, estimated error 0 us,
  status 0x1 (PLL),
  time constant 2, precision 1.000 us, tolerance 512 ppm,
[root@srvname ~]#

Разница во времени - моя проблема
