Como configurar o hwclock para o UTC no Redhat Linux?

2

Eu tenho o redhat linux

# more /etc/redhat-release
Red Hat Enterprise Linux Server release 5.11 (Tikanga)

Eu quero alterar o hwclock para hora UTC

Então eu faço um pequeno teste como

# date -u
Tue Jul 26 10:01:53 UTC 2016

more /etc/sysconfig/clock
ZONE="Asia/Tokyo"

hwclock --show
Tue Jul 26 19:02:17 2016  -0.768566 seconds

E agora vou definir o hwclock para UTC

hwclock --systohc --utc

Mas o hwclock não muda para o tempo UTC ?

# hwclock --show
Tue Jul 26 19:02:56 2016  -0.534987 seconds

Eu também mudo o / etc / sysconfig / clock e anexe a linha UTC = yes

 # vi /etc/sysconfig/clock

 # more /etc/sysconfig/clock
 ZONE="Asia/Tokyo"
 UTC=yes

Mas, de hwclock - show , obtenho UTC tempo

 # hwclock --show
 Tue Jul 26 19:06:56 2016  -0.786752 seconds

Eu tento novamente pelo seguinte comando, mas sem sucesso

 # hwclock --systohc --utc

 # hwclock --show
 Tue Jul 26 19:07:07 2016  -0.399765 seconds

Eu reinicializo a máquina para ver se obtenho UTC hwclock após a reinicialização, mas sem sucesso

 # reboot

 Broadcast message from root (pts/0) (Tue Jul 26 19:07:13 2016):

 The system is going down for reboot NOW!

Após a reinicialização da máquina, executo o seguinte, mas ainda não consigo configurar o hwclock para UTC -: (

 # hwclock --show
 Tue Jul 26 19:11:05 2016  -0.697674 seconds

 # hwclock --systohc --utc

 # hwclock --show
 Tue Jul 26 19:11:15 2016  -0.838524 seconds

Por favor, informe por que não recebo o tempo UTC pelo comando hwclock

Informações da máquina HW

# dmidecode | grep -i hp
       Vendor: HP
       Manufacturer: HP
       Manufacturer: HP
HP ProLiant System/Rack Locator
HP BIOS PXE NIC PCI and MAC Information
HP BIOS iSCSI NIC PCI and MAC Information

Eu corro o hwclock com o debug como:

  hwclock --systohc --utc --debug
  hwclock from util-linux-2.13-pre7
  Using /dev/rtc interface to clock.
  Last drift adjustment done at 1469527871 seconds after 1969
  Last calibration done at 1469527871 seconds after 1969
  Hardware clock is on UTC time
  Assuming hardware clock is kept in UTC time.
  Waiting for clock tick...
  /dev/rtc does not have interrupt functions. Waiting in loop for time   from /dev/rtc to change
 ...got clock tick
  Time read from Hardware Clock: 2016/07/26 11:17:36
  Hw clock time : 2016/07/26 11:17:36 = 1469531856 seconds since 1969
  Time elapsed since reference time has been 0.993984 seconds.
  Delaying further to reach the next full second.
  Setting Hardware Clock to 11:17:36 = 1469531856 seconds since 1969
  ioctl(RTC_SET_TIME) was successful.
  Not adjusting drift factor because it has been less than a day since the   last calibration.
