No, what you said was "negative four days, positive 3605 seconds". Why does it make sense to normalize 3605 seconds to "1 hour, 5 seconds", but not extend that normalization to the days portion? > Complicating things are that timedelta objects are normalized internally so > that > the seconds field is always non-negative The whole idea of datatypes is to hide the internal representation. If it's convenient on your platform, you can store timedeltas internally as fempto-years. That should not affect how it prints. -- https://mail.python.org/mailman/listinfo/python-list
