+# 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

+#
+# 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@vircio.com>

+#
+# 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@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@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.
