hi list,
While porting a glibc application to AIX i found a incompartibility in 
This was discussed recently on comp.sys.aix. I thing the results should be 
noted in the info/man-pages because it may concern more systems than just AIX.

jon wrote a variation on my org. theme:
from: address@hidden (Jon Parmet)

#include <time.h>
#include <stdio.h>

struct tm the_time;
char tt[20];
the output produced is:
Sun Jan  0 00:00:80 1900

It works fine with glibc6, but the AIX guy have also there point:

/* again: jon@ */

FWIW, the Single-Unix specification for strptime says:
The format is composed of zero or more directives. Each
directive is composed of one of the following: one or more
white-space characters (as specified by isspace(); an ordinary
character (neither % nor a white-space character); or a
conversion specification. Each conversion specification is
composed of a % character followed by a conversion character
which specifies the replacement required. There must be
white-space or other non-alphanumeric characters between any
two conversion specifications. ...

I am pretty sure that different standards differ in these point but the 
man-page should be clear and say something like ..

"in extension to the Single-Unix specification the glibc strptime() also 
supports no white-spaces in format strings e.g.: 
strptime(tt,"%d%m%Y%H%M%S",&the_time); "

btw: i prefer the glibc-version

hope that helps.
