It is not known why the server is on the wrong system time, nearly 63 minutes faster than the actual UTC. It is easy to confuse when a timestamp checksum is involved in a local file and a remote server file.

Here, the process of correcting the system time is recorded as follows.

In CentOS 7 there is a command timedatectl can help us modify the server's time zone.

1. View the time set timedatectl in the server, which is equivalent to 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:mo  n 2016-08-29 08:18:07 time
Zone:asia/shanghai (CST, +0800)
NTP enabled:yes
NTP synchronized:no
RTC Local Tz:no
DST active:n/a

2. Understand the parameters of the TIMEDATECTL command:

$ timedatectl-h
