<title>Description</title>
<para><filename>systemd-timesyncd</filename> 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.</para>
