Description
systemd-timesyncd is a
- system service that may be used to synchronize the local
- system clock with a Network Time Protocol Server.
+ 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.conf5,
+ the per-link static settings in
+ .network files, and the per-link
+ dynamic settings received over DHCP. See
+ systemd.network5
+ for more details.
