<title>Description</title>
|
|
|
|
<para><filename>systemd-time-wait-sync</filename> is a system service that delays the start of units that depend on
|
|
<filename>time-sync.target</filename> until the system time has been synchronized with an accurate time source by
|
|
<filename>systemd-timesyncd.service</filename>.</para>
|
|
|
|
<para><filename>systemd-timesyncd.service</filename> notifies on successful synchronization.
|
|
<filename>systemd-time-wait-sync</filename> also tries to detect when the kernel marks the time as synchronized,
|
|
but this detection is not reliable and is intended only as a fallback for other services that can be used to
|
|
synchronize time (e.g., ntpd, chronyd).</para>
