The easiest would be to just set your -j and -k params appropriately, or
setup and synchronize related computers regularly to an ntp server, which
I'm assuming you are doing.

See the help dialog below:

Usage: check_ntp -H <host> [-w <warn>] [-c <crit>] [-j <warn>] [-k <crit>]
[-v verbose]

Checks the local timestamp offset versus <host> with ntpdate
Checks the jitter/dispersion of clock signal between <host> and its
sys.peer with ntpq

-w ( --warning)
     Clock offset in seconds at which a warning message will be generated.
        Defaults to 60.
-c (--critical) 
     Clock offset in seconds at which a critical message will be generated.
        Defaults to 120.
-j (--jwarn)
     Clock jitter in milliseconds at which a warning message will be
generated.        Defaults to 5000.
-k (--jcrit)
    Clock jitter in milliseconds at which a warning message will be
generated.        Defaults to 10000.
    
    If jitter/dispersion is specified with -j or -k and ntpq times out,
then a    warning is returned.
