In 6.9, time:
"""Additional directives may be supported on certain platforms, but only 
the ones listed here have a meaning standardized by ANSI C. 

On some platforms, an optional field width and precision specification can 
immediately follow the initial "%" of a directive in the following order; 
this is also not portable. The field width is normally 2 except for %j 
where it is 3"""

The meaning of the additional directives is not in the Python 
documentation: I used MSDN for that. Microsoft's runtime doesn't support 
field width and precision, but does use the # flag.

In case you didn't know, time.strftime calls the underlying C runtime 
strftime with a buffer 256 times longer than the format string (since there 
is no way to know how long a buffer is required).

"\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure?
