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

## SYNOPSIS
       systemd-time-wait-sync.service

       /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)](https://www.chedong.com/phpMan.php/man/systemd.special/7/markdown) 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.
