systemd-timesyncd.service, systemd-timesyncd — Network Time Synchronization
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
the per-link static settings in
.network files, and the per-link
dynamic settings received over DHCP. See
for more details.
