 Always use the english version in the source code.
 
-### Date and time translation
-
-Date strings use the function `strftime()` to format the date.
-
-For example, the original English version can be defined like that `Created on %B %e, %Y at %k:%M %p` and that will output something like that `Created on January 11, 2015 at 15:19 PM`. The French version can be modified to display a different format, `Créé le %d/%m/%Y à %H:%M` and the result will be `Créé le 11/01/2015 à 15:19`.

-All formats are available in the [PHP documentation](http://php.net/strftime).
