#
# (c)1999 Ian Cass, Knowledge Matters Ltd.
# Read the GNU copyright stuff for all the legalese
#
# 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@vircio.com>
# 22-10-99, 12:17
#
# Modified the script to give usage 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.
#
# Modified 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.
