If you are running a dedicated server and seems server’s time is delayed or is ahead of the actual time, we can use NTP to solve it.
[text]
# yum install ntp
# ntpdate pool.ntp.org
or
# ntpdate 0.fedora.pool.ntp.org
You can also add it to /etc/cron.daily to check correct Date/Time.
# cd /etc/cron.daily/
# vim ntp.sh
#!/bin/bash
/usr/sbin/ntpdate pool.ntp.org
Save and exit the file. Now, make it as a executable by,
# chmod 755 /etc/cron.daily/ntp.sh
Finally restart the cron daemon.
# service crond restart
