While the idea sounds nice that the tag name is the class, this means the
serialization includes whether something is mutable or immutable. This means
doing as much as making something immutable changes the serialization, which
can then cause issues after being deserialized. file: [5d6447d0f7] check-in: [6ce0093f8d] user: js, branch: trunk, size: 9843 [annotate] [blame] [check-ins using] [diff]

This means all other initializers use this initializer, which means all
other initializers can be reused for tagged pointers. file: [c713751502] check-in: [33a133cda0] user: js, branch: tagged-pointers, size: 9325 [annotate] [blame] [check-ins using] [diff]

This replaces all ivar accesses with calls to -[timeIntervalSince1970]
(except for initializers and -[timeIntervalSince1970] itself, which is
the only method accessing an ivar and will be overridden for tagged
pointers), returns a placeholder for +[alloc] and makes +[distantFuture]
and +[distantPast] singletons. file: [8f39732833] check-in: [95830bf78b] user: js, branch: tagged-pointers, size: 9295 [annotate] [blame] [check-ins using] [diff]

This allows ABI stability with the fragile ABI. file: [ef356199a7] check-in: [496695d778] user: js, branch: trunk, size: 9267 [annotate] [blame] [check-ins using] [diff]

This improves Swift compatibility. file: [c8a7ef20f0] check-in: [f3ccf14461] user: js, branch: trunk, size: 8851 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [728f213f2d] check-in: [2f4e0df8be] user: js, branch: trunk, size: 9465 [annotate] [blame] [check-ins using] [diff]

Some time zones have an offset that is not just full hours. file: [fcd33a4a3b] check-in: [da9b9d7e3b] user: js, branch: trunk, size: 9391 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [7c2a95ab3f] check-in: [4af49a13c3] user: js, branch: trunk, size: 9251 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [62d7433493] check-in: [44f45c2e35] user: js, branch: trunk, size: 9215 [annotate] [blame] [check-ins using] [diff]

This adds %z for parsing time zones. Additionally, this also adds %a and
%b. file: [7fa1e30f2a] check-in: [e4439b7ef8] user: js, branch: trunk, size: 9209 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [e2abd5c33f] check-in: [cec0f072f8] user: js, branch: 0.8, size: 9161 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [3a586242e7] check-in: [2a27cf3000] user: js, branch: trunk, size: 9165 [annotate] [blame] [check-ins using] [diff]

This is used instead for time intervals now instead of doubles. file: [496c98e81f] check-in: [dc31ce3d34] user: js, branch: trunk, size: 9059 [annotate] [blame] [check-ins using] [diff]

If the argument is nil, it will return the receiver. file: [a41dd96043] check-in: [38dda0d1c7] user: js, branch: trunk, size: 8938 [annotate] [blame] [check-ins using] [diff]

* Don't expose time_t to the user.
* Use better return types for -[minute] etc.
* Add +[dateWithTimeIntervalSinceNow:].
* Add -[dateByAddingTimeInterval:]. file: [5536148640] check-in: [c084907c2c] user: js, branch: trunk, size: 5263 [annotate] [blame] [check-ins using] [diff]
