__DATE__ and __TIME__ are included in both ANSI
C89 and C99 as predefined macro names.

__DATE__ The date of translation of the source
         file (a character string literal of the
         form "Mmm dd yyyy", where the names of
         the months are the same as those generate
         by the asctime function, and the first
         character of dd is a space character if
         the value is less than 10). If the date of
         translation is not available, an
         implementation-defined valid date shall
         be supplied.

__TIME__ The time of translation of the source
         file (a character string literal of the
         form "hh:mm:ss" as in the time generated
         by the asctime function). If the time of
         translation is not available, an
         implementation-defined valid time shall
         be supplied.

However, it is not clear that this format or value is what
the original requestor desired.
