Because the current status is inconsistent. It currently does different 
things on different systems.

Just adding a flag to suppress the trailing "Z" seems a bit daft to me, 
as it just dumps all the responsibility into the user's lap to get 
things working properly, when we could just as well implement a 
mechanism that does everything right out of the box, while not being any 
more complex - from the user's point of view.

Maybe you're confuzzled by the fact that I've described impementation 
details, not just what the user sees in a standard use case.

If you can describe a system of such functions that works consistently, 
and is reasonably foolproof to use, then I'd be happy to take it into 

As it currently stands, this sounds like a system with a couple of 
building blocks but no mortar to properly tie them together, so the user 
has to mix their own and hope that it's suited for the task.

Pitfalls are plenty in the world of time and timezones, so I'd prefer 
users not have to worry about it themselves (unless they know what they 
are doing and consciously decide to do their own worrying).

For the time being (no pun intended), daylight savings time does exist 
as an undeniable fact of life we have to put up with. If we try to 
ignore it, we will produce a program that breaks at least half of the 
time in half of the world.
