' "System Uptime", by Harold "Waldo" Grunenwald (waldo@ge.com, harold.grunenwald@gmail.com)
' Gives a target system's uptime
' Version 1.01
' Changes: Initial Values for Days, Hours, and Minutes.  Changed spacing.
' Level of Fun Writing This:  High
' ==================================================================================================
' Usage:  Run script from the command line with a servername as an argument.  If no argument is
'            provided, script assumes localhost.
