When we want to know the local timezone offset at a given timestamp, we compute it by asking for localtime() at the given time, and comparing the offset to GMT at that time. However, there's some juggling between time_t and "struct tm" which happens, which involves calling our own tm_to_time_t(). If that function returns an error (e.g., because it only handles dates up to the year 2099), it returns "-1", which we treat as a time_t, and is clearly bogus, leading to bizarre timestamps (that seem to always adjust the time back to (time_t)(uint32_t)-1, in the year 2106). It's not a good idea for local_tzoffset() to simply die here; it would make it hard to run "git log" on a repository with funny timestamps. Instead, let's just treat such cases as "zero offset".
