.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 /usr/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 [**systemd.special**(7)](/man/os/systemd/systemd.special.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

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

Added in version 239.
