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