Doing all storage and computation in UTC does not work if you are dealing with events in the future that need a fixed local time even if time zone offsets change.
As a collector of edge cases and other 'valuable weirdness', I'm at a loss to picture such a use case short of some obscure archival process with interoperability constraints... can you elaborate to clarify when this may be a problem?
I was fairly sure ISO8601 with correct timezone information for every item, was completely sufficient for all my time needs, so if theres something it fails at, id like to know more.
