Re: sort timestamps with associated names.

Just for fun and not to be taken too seriously, here is a "Pseudo-Schwartzian" solution:

use strict;
use warnings;

print    map { /^(.{19})(.*)$/; "$2$1\n" } sort map { /^(.*)(.{19})$/;
+ "$2$1" } <DATA>;

__DATA__

UPDATE: -- for me for not realizing that choroba had posted the same thing above already: Re: sort timestamps with associated names.

This is not ST, it is Guttman Rosler.
