<title>Description</title>
<para><filename>elogind-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>elogind-timesyncd.service</filename>.</para>
<para><filename>elogind-timesyncd.service</filename> notifies on successful synchronization.
<filename>elogind-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 servies that can be used to
synchronize time (e.g., ntpd, chronyd).</para>
