Differences From Artifact [1c4647d564]:

To Artifact [81bcdf5816]:

  • File src/OFDate.m — part of check-in [95830bf78b] at 2020-07-25 09:58:24 on branch tagged-pointers — 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]
