The idea of adding an optional argument to  time.strftime() was
discussed on python-dev, but did not get much traction there:

I wish we didn't have to do that -- isn't it easy enough for the app
to do the 2d -> 4d conversion itself before calling the library
function? The only exception would be when parsing a string -- but
strptime can tell whether a 2d or 4d year is requested by the format
code (%y or %Y).
