Do note that time_t structures typically contain "year" elements that are less than 64 bits wide; when this is the case, very very negative and very very positive time_t values are associated with years that can't be represented using time_t's; this is why zdump shows "NULL" for these values.

Looking further, I'm getting particularly nonsensical output for some
timezones. It doesn't seem that useful, even if it is the expected

$ zdump -v EST
EST  -9223372036854775808 = NULL
EST  -9223372036854689408 = NULL
EST  9223372036854689407 = NULL
EST  9223372036854775807 = NULL
