/*
* Internal ascii conversion routine, avoid use of printf, it's a bit big!
*/
/*
* Modified Manuel Novoa III Jan 2001
*
* Removed static function "hit" and did time-field fills inline and
* put day, hour, min, and sec conversions in a loop using a small
* table to reduce code size.
*
* Made daysp[] and mons[] const to move them from bss to text.
*
* Also fixed day conversion ... ANSI says no leading 0.
*
* Modified Erik Andersen May 2002
* Changed to optionally support real locales.
*
