<title>Description</title>
|
|
|
|
<para><filename>systemd-time-wait-sync</filename> is a system service that delays the start of units that
|
|
are ordered after <filename>time-sync.target</filename> (see
|
|
<citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry> for
|
|
details) until the system time has been synchronized with an accurate remote reference time source by
|
|
<filename>systemd-timesyncd.service</filename>.</para>
|
|
|
|
<para><filename>systemd-timesyncd.service</filename> notifies <filename>systemd-time-wait-sync</filename>
|
|
about successful synchronization. <filename>systemd-time-wait-sync</filename> also tries to detect when
|
|
the kernel marks the system clock as synchronized, but this detection is not reliable and is intended
|
|
only as a fallback for compatibility with alternative NTP services that can be used to synchronize time
|
|
(e.g., ntpd, chronyd).</para>
