NAME
systemd-timesyncd.service, systemd-timesyncd - Network Time Synchronization
SYNOPSIS
systemd-timesyncd.service
/lib/systemd/systemd-timesyncd
DESCRIPTION
systemd-timesyncd is a system service that may be used to synchronize the local system
clock with a remote Network Time Protocol server. It also saves the local time to disk
every time the clock has been synchronized and uses this to possibly advance the system
realtime clock on subsequent reboots to ensure it monotonically advances even if the
system lacks a battery-buffered RTC chip.
The NTP servers contacted are determined from the global settings in timesyncd.conf(5),
the per-link static settings in .network files, and the per-link dynamic settings received
over DHCP. See systemd.network(5) for more details.
timedatectl(1)'s set-ntp command may be used to enable and start, or disable and stop this
service.
