Wow, that's a really interesting case. I guess the same thing would happen whenever an offset was adjusted after you store a value in UTC intended for another timezone. I don't think this is even supported by Django - all times are converted to UTC on entry to the database.

Yep, or if a DST change was added or rescinded (which can happen on surprisingly short orders, many governments love fucking up with DST, this year 2016 we got an infirmation of Egyptian DST with 3 days lead time).
