-# x.s = x's standard offset, x.o - x.d
-#
-# Now some derived rules, where k is a duration (timedelta).
-#
-# 1. x.o = x.s + x.d
-# This follows from the definition of x.s.
-#
-# 2. If x and y have the same tzinfo member, x.s = y.s.
-# This is actually a requirement, an assumption we need to make about
-# sane tzinfo classes.
-#
-# 3. The naive UTC time corresponding to x is x.n - x.o.
-# This is again a requirement for a sane tzinfo class.
-#
-# 4. (x+k).s = x.s
-# This follows from #2, and that datimetimetz+timedelta preserves tzinfo.
-#
-# 5. (x+k).n = x.n + k
-# Again follows from how arithmetic is defined.
-#
-# Now we can explain tz.fromutc(x). Let's assume it's an interesting case
-# (meaning that the various tzinfo methods exist, and don't blow up or return
-# None when called).
-#
-# The function wants to return a datetime y with timezone tz, equivalent to x.
-# x is already in UTC.
-#
-# By #3, we want
-#
-# y.n - y.o = x.n [1]
-#
-# The algorithm starts by attaching tz to x.n, and calling that y. So
-# x.n = y.n at the start. Then it wants to add a duration k to y, so that [1]
-# becomes true; in effect, we want to solve [2] for k:
-#
-# (y+k).n - (y+k).o = x.n [2]
-#
-# By #1, this is the same as
-#
-# (y+k).n - ((y+k).s + (y+k).d) = x.n [3]
-#
-# By #5, (y+k).n = y.n + k, which equals x.n + k because x.n=y.n at the start.
-# Substituting that into [3],
-#
-# x.n + k - (y+k).s - (y+k).d = x.n; the x.n terms cancel, leaving
-# k - (y+k).s - (y+k).d = 0; rearranging,
-# k = (y+k).s - (y+k).d; by #4, (y+k).s == y.s, so
-# k = y.s - (y+k).d
-#
-# On the RHS, (y+k).d can't be computed directly, but y.s can be, and we
-# approximate k by ignoring the (y+k).d term at first. Note that k can't be
-# very large, since all offset-returning methods return a duration of magnitude
-# less than 24 hours. For that reason, if y is firmly in std time, (y+k).d must
-# be 0, so ignoring it has no consequence then.
-#
-# In any case, the new value is
-#
-# z = y + y.s [4]
-#
-# It's helpful to step back at look at [4] from a higher level: it's simply
-# mapping from UTC to tz's standard time.
-#
-# At this point, if
-#
-# z.n - z.o = x.n [5]
-#
-# we have an equivalent time, and are almost done. The insecurity here is
-# at the start of daylight time. Picture US Eastern for concreteness. The wall
-# time jumps from 1:59 to 3:00, and wall hours of the form 2:MM don't make good
-# sense then. The docs ask that an Eastern tzinfo class consider such a time to
-# be EDT (because it's "after 2"), which is a redundant spelling of 1:MM EST
-# on the day DST starts. We want to return the 1:MM EST spelling because that's
-# the only spelling that makes sense on the local wall clock.
-#
-# In fact, if [5] holds at this point, we do have the standard-time spelling,
-# but that takes a bit of proof. We first prove a stronger result. What's the
-# difference between the LHS and RHS of [5]? Let
-#
-# diff = x.n - (z.n - z.o) [6]
-#
-# Now
-# z.n = by [4]
-# (y + y.s).n = by #5
-# y.n + y.s = since y.n = x.n
-# x.n + y.s = since z and y are have the same tzinfo member,
-# y.s = z.s by #2
-# x.n + z.s
-#
-# Plugging that back into [6] gives
-#
-# diff =
-# x.n - ((x.n + z.s) - z.o) = expanding
-# x.n - x.n - z.s + z.o = cancelling
-# - z.s + z.o = by #2
-# z.d
-#
-# So diff = z.d.
-#
-# If [5] is true now, diff = 0, so z.d = 0 too, and we have the standard-time
-# spelling we wanted in the endcase described above. We're done. Contrarily,
-# if z.d = 0, then we have a UTC equivalent, and are also done.
-#
-# If [5] is not true now, diff = z.d != 0, and z.d is the offset we need to
-# add to z (in effect, z is in tz's standard time, and we need to shift the
-# local clock into tz's daylight time).
-#
-# Let
-#
-# z' = z + z.d = z + diff [7]
-#
-# and we can again ask whether
-#
-# z'.n - z'.o = x.n [8]
-#
-# If so, we're done. If not, the tzinfo class is insane, according to the
-# assumptions we've made. This also requires a bit of proof. As before, let's
-# compute the difference between the LHS and RHS of [8] (and skipping some of
-# the justifications for the kinds of substitutions we've done several times
-# already):
-#
-# diff' = x.n - (z'.n - z'.o) = replacing z'.n via [7]
-# x.n - (z.n + diff - z'.o) = replacing diff via [6]
-# x.n - (z.n + x.n - (z.n - z.o) - z'.o) =
-# x.n - z.n - x.n + z.n - z.o + z'.o = cancel x.n
-# - z.n + z.n - z.o + z'.o = cancel z.n
-# - z.o + z'.o = #1 twice
-# -z.s - z.d + z'.s + z'.d = z and z' have same tzinfo
-# z'.d - z.d
-#
-# So z' is UTC-equivalent to x iff z'.d = z.d at this point. If they are equal,
-# we've found the UTC-equivalent so are done. In fact, we stop with [7] and
-# return z', not bothering to compute z'.d.
-#
-# How could z.d and z'd differ? z' = z + z.d [7], so merely moving z' by
-# a dst() offset, and starting *from* a time already in DST (we know z.d != 0),
-# would have to change the result dst() returns: we start in DST, and moving
-# a little further into it takes us out of DST.
-#
-# There isn't a sane case where this can happen. The closest it gets is at
-# the end of DST, where there's an hour in UTC with no spelling in a hybrid
-# tzinfo class. In US Eastern, that's 5:MM UTC = 0:MM EST = 1:MM EDT. During
-# that hour, on an Eastern clock 1:MM is taken as being in standard time (6:MM
-# UTC) because the docs insist on that, but 0:MM is taken as being in daylight
-# time (4:MM UTC). There is no local time mapping to 5:MM UTC. The local
-# clock jumps from 1:59 back to 1:00 again, and repeats the 1:MM hour in
-# standard time. Since that's what the local clock *does*, we want to map both
-# UTC hours 5:MM and 6:MM to 1:MM Eastern. The result is ambiguous
-# in local time, but so it goes -- it's the way the local clock works.
-#
-# When x = 5:MM UTC is the input to this algorithm, x.o=0, y.o=-5 and y.d=0,
-# so z=0:MM. z.d=60 (minutes) then, so [5] doesn't hold and we keep going.
-# z' = z + z.d = 1:MM then, and z'.d=0, and z'.d - z.d = -60 != 0 so [8]
-# (correctly) concludes that z' is not UTC-equivalent to x.
-#
-# Because we know z.d said z was in daylight time (else [5] would have held and
-# we would have stopped then), and we know z.d != z'.d (else [8] would have held
-# and we have stopped then), and there are only 2 possible values dst() can
-# return in Eastern, it follows that z'.d must be 0 (which it is in the example,
-# but the reasoning doesn't depend on the example -- it depends on there being
-# two possible dst() outcomes, one zero and the other non-zero). Therefore
-# z' must be in standard time, and is the spelling we want in this case.
-#
-# Note again that z' is not UTC-equivalent as far as the hybrid tzinfo class is
-# concerned (because it takes z' as being in standard time rather than the
-# daylight time we intend here), but returning it gives the real-life "local
-# clock repeats an hour" behavior when mapping the "unspellable" UTC hour into
-# tz.
-#
-# When the input is 6:MM, z=1:MM and z.d=0, and we stop at once, again with
-# the 1:MM standard time spelling we want.
-#
-# So how can this break? One of the assumptions must be violated. Two
-# possibilities:
-#
-# 1) [2] effectively says that y.s is invariant across all y belong to a given
-# time zone. This isn't true if, for political reasons or continental drift,
-# a region decides to change its base offset from UTC.
-#
-# 2) There may be versions of "double daylight" time where the tail end of
-# the analysis gives up a step too early. I haven't thought about that
-# enough to say.
-#
-# In any case, it's clear that the default fromutc() is strong enough to handle
-# "almost all" time zones: so long as the standard offset is invariant, it
-# doesn't matter if daylight time transition points change from year to year, or
-# if daylight time is skipped in some years; it doesn't matter how large or
-# small dst() may get within its bounds; and it doesn't even matter if some
-# perverse time zone returns a negative dst()). So a breaking case must be
-# pretty bizarre, and a tzinfo subclass can override fromutc() if it is.
