os.stat - time format conversion + md5

[P_spam_ at draigBrady.com]

I'm a bit confused about what you want. Why can't you just compare
the output from os.stat() for both files. Why the human readable
requirement?

Also I can't see why the date has anything to do with it unless
you're doing a 2 way sync. Anyway if I was you...

if both src and dest filenames exist
    stat both
    if sizes same
        just copy because crc will be slower

Have you looked at rsync?
