NAME

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

SYNOPSIS

       systemd-time-wait-sync.service

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

DESCRIPTION

       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) 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

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

           Added in version 239.
