未知何故,服务器上的系统时间不对,比实际的UTC快了将近63分钟。在涉及本地文件与远程服务器文件的时间戳校验时,容易产生混淆。
这里把系统时间更正的过程记录如下。

在CentOS 7里面有一个命令timedatectl可以帮助我们修改服务器的时区。
1. 查看服务器里的时间设置 timedatectl ,它等同于 timedatectl status :
$ timedatectl Local time: Mon 2016-08-29 16:20:35 CST Universal time: Mon 2016-08-29 08:20:35 UTC RTC time: Mon 2016-08-29 08:18:07 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: yes NTP synchronized: no RTC in local TZ: no DST active: n/a
2. 了解 timedatectl 命令的各个参数:
$ timedatectl -h timedatectl [OPTIONS...] COMMAND ... Query or change system time and date settings. -h --help Show this help message --version Show package version --no-pager Do not pipe output into a pager --no-ask-password Do not prompt for password -H --host=[[email protected]]HOST Operate on remote host -M --machine=CONTAINER Operate on local container --adjust-system-clock Adjust system clock when changing local RTC mode Commands: status Show current time settings set-time TIME Set system time set-timezone ZONE Set system time zone list-timezones Show known time zones set-local-rtc BOOL Control whether RTC is in local time set-ntp BOOL Control whether NTP is enabled
3. 设置时间
$ sudo timedatectl set-time 15:26:58$ timedatectl Local time: Mon 2016-08-29 15:27:00 CST Universal time: Mon 2016-08-29 07:27:00 UTC RTC time: Mon 2016-08-29 07:27:00 Time zone: Asia/Shanghai (CST, +0800) NTP enabled: no NTP synchronized: no RTC in local TZ: no DST active: n/a
结束。
