That may be so according to the most recent 8601 standard, but as far as Perl is concerned it is not. For example, Date::Manip claims to be able to handle ISO 8601 date formats, but the following will fail: 
use strict;
use Date::Manip;
 
my $string = "2004-11-15T18:59:52.863Z";
my $date = ParseDate($string);
print $date,"\n";
