--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note the path to hit this is __TIMESTAMP__ .

                /* Generate __TIMESTAMP__ string, that represents
                   the date and time of the last modification
                   of the current source file. The string constant
                   looks like "Sun Sep 16 01:03:52 1973".  */

if I did this correctly then the format should be:

"%a %b %d %T %Y\n"
