It seems so -- at least under the proposals I've seen so far, as if consumers are running software derived from tzcode, they would need to upgrade, as otherwise the code would mishandle some timestamps. I haven't looked at non-tzcode-derived libraries but I expect many would be similar. We'd rather avoid this, of course.
While avoiding a version bump is desirable, it's not always possible. It seems to me that the pain of a version bump could be ameliorated by having both * new code able to read and process both old and new versions, and * zic growing a new option to produce either old or new "compiled" versions of the zone files (default version TBD) +------------------+--------------------------+------------------------+ | Paul Goyette | PGP Key fingerprint: | E-mail addresses: | | (Retired) | FA29 0E3B 35AF E8AE 6651 | paul at whooppee.com | | Kernel Developer | 0786 F758 55DE 53BA 7731 | pgoyette at netbsd.org | +------------------+--------------------------+------------------------+
