            "content": "systemd-time-wait-sync is a system service that delays the start of units that are ordered\nafter time-sync.target (see systemd.special(7) for details) until the system time has been\nsynchronized with an accurate remote reference time source by systemd-timesyncd.service.\n\nsystemd-timesyncd.service notifies systemd-time-wait-sync about successful synchronization.\nsystemd-time-wait-sync also tries to detect when the kernel marks the system clock as\nsynchronized, but this detection is not reliable and is intended only as a fallback for\ncompatibility with alternative NTP services that can be used to synchronize time (e.g., ntpd,\nchronyd).\n",
