-#
-# Check NTP time servers plugin. This plugin requires the ntpdate utility to
-# be installed on the system, however since it's part of the ntp suite, you
-# should already have it installed.
-#
-#
-# Nothing clever done in this program - its a very simple bare basics hack to
-# get the job done.
-#
-# Things to do...
-# check @words[9] for time differences greater than +/- x secs & return a
-# warning.
-#
-# (c) 1999 Mark Jewiss, Knowledge Matters Limited
-# 22-9-1999, 12:45
-#
-# Modified script to accept 2 parameters or set defaults.
-# Now issues warning or critical alert is time difference is greater than the
-# time passed.
-#
-# These changes have not been tested completely due to the unavailability of a
-# server with the incorrect time.
-#
-# (c) 1999 Bo Kersey, VirCIO - Managed Server Solutions <bo at vircio.com>
-# 22-10-99, 12:17
-#
-# Modified the script to give useage if no parameters are input.
-#
-# Modified the script to check for negative as well as positive
-# time differences.
-#
-# Modified the script to work with ntpdate 3-5.93e Wed Apr 14 20:23:03 EDT 1999
-#
-# Modified the script to work with ntpdate's that return adjust or offset...
-#
-#
-# Script modified 2000 June 01 by William Pietri <william at bianca.com>
-#
-# Modified script to handle weird cases:
-# o NTP server doesn't respond (e.g., has died)
-# o Server has correct time but isn't suitable synchronization
-# source. This happens while starting up and if contact
-# with master has been lost.
-#
-# Modifed to run under Embedded Perl (sghosh at users.sf.net)
-# - combined logic some blocks together..
-#
-# Added ntpdate check for stratum 16 desynch peer (James Fidell) Feb 03, 2003
-#
-# ntpdate - offset is in seconds
-# changed ntpdc to ntpq - jitter/dispersion is in milliseconds
-#
-# Patch for for regex for stratum1 refid.
