NTP
Network Time Protocol. This will make your system date match actual date, by synchronizing with network time servers.
systemd-timesyncd acts as a NTP client even when no network is available. This is enough to synchronize a system. NTP deamon is required only when a NTP server is required. See Freedesktop.org's page on timesyncd for more details
Install and Configure
- Type date to see current date and time. (Use -R to get a standard unambiguous format. Locale specific timezones are ambiguous.)
date -R
- Install NTP
aptitude install ntp
- Done.
Type ntpq -p to see servers you are syncing with.
Type date again to see if the time changed. You time should be synced in a next minute.
- Done.
Troubleshooting
If you run ntpq -p and you get
No association ID's returned
- Run
dpkg-reconfigure ntp
- And then again:

Public Internet Time Servers
The Debian package will install a default set of time servers which should be good for most typical client installations. However you may customize this for your network location. A good source of NTP pool information is the NTP Pool Project.
