Not sure if this is of use or not - we have a strange requirement to run certain servers 5 minutes fast. I've added a switch to the check_ntp_time to allow for this offset.

Patch against Plugin Version (-V output):
check_ntp_time vtrunk.2244.dirty (nagios-plugins 1.4.14)
Plugin Name:
check_ntp_time
Example Plugin Commandline:
check_ntp_time -H ntp2c.mcc.ac.uk -o 500
Tested on operating system:
CentOS release 5.3 (Final)
Tested on architecture:
x86_64
Tested with compiler:
gcc version 4.1.2 20080704 (Red Hat 4.1.2-44)

That doesn't sound right... What is your use case for this? can you show the verbose output of two runs, one with and one without that option?

Thank you.
