NAME top

   systemd-time-wait-sync.service, systemd-time-wait-sync - Wait
   until kernel time is synchronized

SYNOPSIS top

   systemd-time-wait-sync.service

   /usr/lib/systemd/systemd-time-wait-sync

DESCRIPTION top

   systemd-time-wait-sync is a system service that delays the start
   of units that are ordered after time-sync.target (see
   [systemd.special(7)](../man7/systemd.special.7.html) for details) until the system time has been
   synchronized with an accurate remote reference time source by
   systemd-timesyncd.service.

   systemd-timesyncd.service notifies systemd-time-wait-sync about
   successful synchronization.  systemd-time-wait-sync 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).

FILES top

   /run/systemd/timesync/synchronized
       The presence of this file indicates to this service that the
       system clock has been synchronized.

       Added in version 239.
