# Returns the store times for all metadata. (ie. creation, modified, archived, accessed and metadata modified time).
# 
# The script requires the name of a file, complete with slash and path.
#  
# This script has been designed to be run on NetWare. 
# The API set can be downloaded from  http://developer.novell.com/wiki/index.php/Virtual_File_Services_for_NetWare. 
# 
#
# The Perl script requires the name of an NSS volume as input.  It requires that NSS be installed and an NSS volume be present.
