[issue34642] time.ctime() uses %3d instead of %.2d to format.

[Martin Panter]

Martin Panter  added the comment:

I think "ctime" and "asctime" are supposed to wrap or imitate the standard C 
functions: , so I think this 
is intended behaviour. But see Issue 13927 about improving the documentation.

For a single-digit day of the month, there is supposed to be two spaces. Using 
"%.2d" would produce "Sep02" or "Sep 02", with a leading zero. On the other 
hand, changing the double space to a single space would produce "Sep 2", 
without a leading zero.

It's easy to get around using .replace('  ', ' '), but it's still a bit 
annoying.

[issue34642] time.ctime() uses %3d instead of %.2d to format.

[William Chaseling]

New submission from William Chaseling :

time.ctime() returns _asctime from a C module.
_asctime returns a PyUnicode_FromFormat() result using "%s %s%3d %.2d:%.2d:%.2d 
%d" as the string formatter.

This works: 'Wed Sep 12 22:30:00 2018'
Except when day <10, because it uses %3d instead of %.2d
'Wed Sep  2 22:30:00 2018'

This seems like it might be intended behavior for some reason, but I don't see 
the reason.
