Nicolas Boullis and Debian users have noticed problems in iso9660 time/date recording and running the regression tests, specifically I suppose testiso9660. He has also generously provided some patches.
However from this there is the lingering question of how tm_gmtoff and tm_isdst interact. Does tm_gmtoff reflect the tm_isdst value if it is 1 or not? (tm_isdt can be -1 which means we don't know, 0 for not in use or 1 for in use) A scan of the Internet doesn't seem to elucidate; neither does looking at manual pages for localtime, etc. Thanks.
