Manage server date and time, ntp server for lan clients.

How it works

When the time and date are modified, some services must be restarted. Each package must subscribe service2adjust interface. Note that there’s no need to restart rsyslog on date and time changing. Rsyslog daemon is smart enough to read new time setting on the fly.

Date and time can be set manually or automatically via a ntp server.

The current time zone is accessible from the configuration database, but the value is read and written using systemd commands.


  • nethserver-ntp-update, standard event triggered on package installation/update.
  • nethserver-ntp-save, standard event triggered on UI module SAVE action


  • nethserver-ntp-localtime, create a lint to the zoneinfo file from /usr/share/zoneinfo to /etc/localtime according to TimeZone key in _configuration_ database.
  • nethserver-ntp-clock-adjust, adjust the system date and hardware clock when NTP is disabled. Requires the event name and timestamp arguments. When NTP is enabled, restarts the ntp daemon.
