In the former, typing '2012.01.01' implicitly creates a date object (probably), and '1m1d' implicitly creates some sort of duration object (probably) and uses an operator to combine them.

The Java was isn't really that different. Just more verbose, but again, I don't mind trading a few key strokes for clarity.

What clarity? That's what I mean. The first example starts with a date then adds values to it. Second does same thing. I use neither language nor do tjme series but still knew tge intent. So all you're getting is extra keystrokes with same clarity.
