No, it didn't lose anything. You are only looking for an illusion there. Our concept of a constant 24 hour, 1440 minute, 86400 second day is simply a lie to make our daily routines easier. We are actually constantly introduced with 86401 second days, 25 hour days and 23 hour days. DateTime correctly computes those as well, and DT::Duration is the way it is because of this. But yes, that's not terribly well documented. (I personally wouldn't have really grasped it until I dived into the code to write my own calendar module) --d
