I just got back from Perl Whirl. Having spent most of the last week plugging DT as a replacement for many of the examples given in the talks, I think we need a converting to DT section in the FAQ or a separate document dedicated to this.
For example (I saw this in many presentations ): use POSIX qw( strftime ); my $time = strftime( "%Y-%m-%d %H:%M:%S", localtime() ); becomes: use DateTime; my $time = DateTime->now->strftime( "%Y-%m-%d %H:%M:%S" ); -J --
