This plugin checks the clock offset between the local host and a
remote NTP server. It is independent of any commandline programs or
external libraries.

Notes:
If you'd rather want to monitor an NTP server, please use
check_ntp_peer.

See:
http://nagiosplug.sourceforge.net/developer-guidelines.html#THRESHOLDFOR...
for THRESHOLD format and examples.

Examples:
./check_ntp_time -H ntpserv -w 0.5 -c 1
