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 systemd-timesyncd service specifically implements only SNTP. This
minimalistic service will set the system clock for large offsets or slowly
adjust it for smaller deltas. More complex use cases are not covered by
The NTP servers contacted are determined from the global settings in

the per-link dynamic settings received over DHCP. See
