Good point. Still, the C standard (which doesn't mention TZ) should not impose a at-most-two-offsets requirement, since that's not how many C implementations actually behave. And once we get the C standard fixed POSIX will follow, and this should allow the common behavior when TZ has a value like "America/Los_Angeles" or ":America/Los_Angeles" that uses our extension to POSIX.
