Agreed with Antoine, strftime/strptime are somewhat different concerns. Doesn't mean thay cannot be fixed at the same time but it's a bit a separate.
Which reminds me... Somewhere else (maybe elsewhere in this thread? maybe on a bug tracker issue?) someone mentioned that Ruby uses %N for fractions of a second (and %L specifically for milliseconds). Here's the bit from the Ruby strftime doc:
%L - Millisecond of the second (000..999) %N - Fractional seconds digits, default is 9 digits (nanosecond) %3N millisecond (3 digits) %6N microsecond (6 digits) %9N nanosecond (9 digits) %12N picosecond (12 digits)
There's no obvious reason I can see to reinvent this particular wheel, at least the %N spoke. The only question might be whether to modify Python's existing %f format to accept a precision (defaulting to 6), or add %N in a manner similar (or identical) to Ruby's semantics.
