Thanks for the proposal.
I do see some clashes within the proposal though:
Right at the start you are mentioning that "An Time\Instant carries no
timezone. It represents a unique point on the timeline of the universe. This
point is the same for everyone, no matter where they are located on the Earth
(or not on Earth at all), i.e. no matter their timezone."
I am totally in favour of that!
Later on though you are mentioning that "Following the lead of virtually all
programming languages and operating systems, leap seconds are ignored."
Is that only with relation to the Iso8601 strings? Or is that a general
shortcoming?
The other point I find irritating is the naming of the `Clock` interface. While
I can understand the reasoning behind it I see irritation in the community
upcoming as the `CLockInterface` now suddenly returns 2 different things,
depending on which ClockInterface people are talking about.
Is there a way to Unify the ideas behind Time\Clock and
Psr\Clock\CLockInterface?
As right now the Time\Clock is not a direct replacement of
Psr\Clock\ClockInterface as - at the current time - there is no way to generate
a DateTimeImmutable directly from a Time\Instant.
Just my 0.02€
Cheers
