[Unit] Description=Wait Until Kernel Time Synchronized Documentation=man:systemd-time-wait-sync.service(8) # Note that this tool doesn't need CAP_SYS_TIME itself, but it's primary # usecase is to run in conjunction with a local NTP service such as # systemd-timesyncd.service, which is conditioned this way. There might be # niche usecases where running this service independently is desired, but let's # make this all "just work" for the general case, and leave it to local # modifications to make it work in the remaining cases.
