.SH "NAME"
systemd-time-wait-sync.service, systemd-time-wait-sync \- Wait until kernel time is synchronized
.SH "SYNOPSIS"
.PP
systemd\-time\-wait\-sync\&.service
.PP
/lib/systemd/systemd\-time\-wait\-sync
.SH "DESCRIPTION"
.PP
systemd\-time\-wait\-sync
is a system service that delays the start of units that are ordered after
time\-sync\&.target
(see
\fBsystemd.special\fR(7)
for details) until the system time has been synchronized with an accurate remote reference time source by
systemd\-timesyncd\&.service\&.
.PP
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)\&.
.SH "FILES"
.PP
/run/systemd/timesync/synchronized
.RS 4
The presence of this file indicates to this service that the system clock has been synchronized\&.
