15 systemd-time-wait-sync is a system service that delays the start of
16 units that are ordered after time-sync.target (see systemd.special(7)
17 for details) until the system time has been synchronized with an
18 accurate remote reference time source by systemd-timesyncd.service.
19
20 systemd-timesyncd.service notifies systemd-time-wait-sync about
21 successful synchronization. systemd-time-wait-sync also tries to
22 detect when the kernel marks the system clock as synchronized, but this
23 detection is not reliable and is intended only as a fallback for
24 compatibility with alternative NTP services that can be used to
25 synchronize time (e.g., ntpd, chronyd).
26
28 /run/systemd/timesync/synchronized
29 The presence of this file indicates to this service that the system
30 clock has been synchronized.
