Yes, (b) is part of my proposal. Sorry I wasn't clear. Because the tzfile format
is independent of the current time and date, (b) follows the format's rules and
should work -- though you're right, some client-code bugs may be exposed by (b).
(a), on the other hand, is not clearly contemplated by tzfile(5), and may well
break non-buggy code in 32-bit clients that never look at the 64-bit data. So it
requires a change to the tzfile format and is a bigger deal.
