NTP out of sync?
Is your unix-based system time out of sync? If it is out of sync by more that 1000 seconds, you will need to manually force it back into sync. Try:
# ntpd -q
to force a re-sync with the ntp time servers specified in your NTP configuration file.
Two issues that may arise:
- Your ntp servers may need updating in your /etc/ntp.conf file (one of many NTP server lists).
- Check if you are being stymied by trying to update from behind a firewall.
Also, you can try using the deprecated ntpdate along with the regional host name that makes the most sense provided with the server name (see list above).
# ntpdate north-america.pool.ntp.org
And finally, use ntpq to check that your offset and jitter aren't too large (times are shown in milliseconds):
# ntpq -p
Check any of the above commands' man pages for an in-depth explanation of each one and it's possible options.
