Different format of __DATE__ macro

C has a predefined macro __DATE__, that shows the date of the compiled source file .
The date is displayed in the format "Mmm dd yyyy" .

Is there any way to be formatted this date, using macros ?
In this format "yyyy Mmm dd".

Instead of being :

Jul 19 2013

Should be :

2013 Jul 19

Solution

  • In C you could have a macro that generates a compound literal on the fly that has the order that you like, something like

    #define FDATE (char const[]){ __DATE__[7], __DATE__[8], ..., ' ', ... , '\0' }

    in all places where it matters your optimizer should be able to handle this efficiently.
