It's a standalone binary, with no config file and no dependency on the *ntp* package. **sntpc** does not run as a daemon like **ntpd** does. To keep the time in sync, you can run **sntpc** from root's **crontab**\(1) every 30 minutes (or however often it's necessary). **sntpc** requires root access to actually set the local clock, although it can be run with **-n** by non-privileged users (e.g. with **-v** to simply check the local time against the server's time). OPTIONS ======= -b Allow time shift backwards (default: forward only). -h Show built-in help message. -n No set time (dry run). -p Set server port number (default: 123). -s Set server name or IPv4 address (default: pool.ntp.org). -t Set maximum time offset threshold (default: 300 seconds). This can be set to a ludicrously high value such as 40000000000 (over 1,000 years) to effectively disable the threshold. -v Verbose (default: silent) COPYRIGHT ========= See the file /usr/doc/sntpc-|version|/LICENSE.txt for license information.
