— OFDate: Prepare for tagged pointers
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. (user: js, size: 18751) [annotate] [blame] [check-ins using]

— OFDate: Add a designated initializer
This means all other initializers use this initializer, which means all
other initializers can be reused for tagged pointers. (user: js, size: 18234) [annotate] [blame] [check-ins using]
