cpython/Lib/test/test_strftime.py
Guido van Rossum 2b41fdccd3 Moved some non-standard format characters out of the standard list.
Also moved %c and %Z out of there, even though they are standard,
because these are locale dependent (and e.g. on Windows and Mac they
return different strings).  Finally, sorted the tables slightly
different, to match my standard docs better (%a before %A).
