Linux 上的硬件时间错误

我的 Debian 服务器上没有正确的硬件时间：

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

我应该怎么办？

root@server[10:04]:vi /etc/ntp.conf

您的时区设置为 EST（东部标准时间），这是纽约的时区，而不是巴黎的时区。巴黎的时间是 CET（中欧时间）。

您必须首先正确设置时区，这可以通过多种方式完成：

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

一旦时区正确，您就可以设置正确的时间（如有必要）。
