0.1ms to parse a date???

Even the standard PHP string parser does 0.017ms on my 3 year old netbook.

    <?php

    $st = microtime(true);
    $cnt = 10000;

    for ($i=0; $i<$cnt; $i++)
    	strtotime('2014-01-09T21:48:00.921000');

    echo 1000 * (microtime(true) - $st) / $cnt;

Seems like this solves a non-existing issue.

You can see the issue it solves pretty clearly here: https://github.com/elasticsales/ciso8601#benchmark

Python != PHP

[imaginenore]

Actually both Python and PHP are ridiculously slow languages. Though Python is slower.

[illumen]

Some implementations of python are slowish for some tasks. Many parts, like the module being discussed are written in C/assembly/fortran/Java.

Python with a jit is Pypy, http://speed.pypy.org/

Also PHP has some fast _implementations_ of PHP.

[grinich]

Languages aren't slow. Interpreters are.

As a human, I can think a lot faster in Python. So for me, it's a faster language.

This also doesn't do the same thing, since you're not constructing a DateTime object.
