linux上錯誤的硬體時間

我的 debian 伺服器上沒有正確的硬體時間：

root@server[09:48]:date
Tue Dec 22 09:48:52 EST 2015

root@server[09:48]:date -u
Tue Dec 22 14:48:54 UTC 2015 

root@server[09:48]:cat /etc/timezone
Europe/Paris

root@server[09:48]:hwclock -w --utc --debug

hwclock from util-linux 2.25.2
Using the /dev interface to the clock.
Last drift adjustment done at 1450795502 seconds after 1969
Last calibration done at 1450795502 seconds after 1969
Hardware clock is on UTC time
Assuming hardware clock is kept in UTC time.
Waiting for clock tick...
...got clock tick
Time read from Hardware Clock: 2015/12/22 14:46:18
Hw clock time : 2015/12/22 14:46:18 = 1450795578 seconds since 1969
1450795578.500007 is close enough to 1450795578.500000 (0.000007 < 0.001000)
Set RTC to 1450795578 (1450795578 + 0; refsystime = 1450795578.000000)
Setting Hardware Clock to 14:46:18 = 1450795578 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.

root@server[09:48]:cat /etc/adjtime

0.000000 1450795578 0.000000
1450795578
UTC

我該怎麼辦？

您的時區設置為 EST（東部標準時間），這是紐約的時區，而不是巴黎的時區。巴黎時間為 CET（中歐時間）。

您必須首先正確設置時區，這可以通過多種方式完成：

• 使用命令tzselect
• 使用命令dpkg-reconfigure tzdata
• 輸入TZ='Europe/Paris'; export TZ您的~/.bash_profile, ~/.bash_login, 或~/.profile

時區正確後，您可以設置正確的時間（如有必要）。
