This is interesting, I wonder if there are more related issues. There is a lot of stuff that embeds timestamps. The first I could think of is the TLS handshake, but it's GMT and several implementations don't set it any more to a valid value (they use a random value instead). Various image formats use timestamps, they seem to be timezone unaware. Probably something to look into, and probably a good idea to question whether we need timestamps everywhere. If they don't serve a useful purpose better skip them. (They also happen to be a major issue with things like reproducible builds.)
