Is that relevant? If my philosophy is weak, you can prove it to be weak by providing me with an example of a library which conforms to a better philosophy; then I can see why it's better.
I won't just say it doesn't satisfy my philosophy. I'll say additionally that the .NET standard library's `DateTime` type, which I believe is essentially the same and uses basically the same primitives, is so hard to use correctly that I have multiple times had to rewrite other people's programs, in one case completely from the ground up, to fix their correctness due to bugs I personally encountered in them in real life. I do have empirical evidence for some of my opinions, you know!
Time handling is one of the many cases where there is actually complexity in the domain, and if you refuse to model the complexity, that doesn't make the complexity go away; it just means you've got bugs.
So it's famously difficult to write a correct date-time handling program, but my empirical observation is that it's considerably easier with a library like Noda Time which actually attempts to model some of the domain beyond "ticks since the epoch".
