>>> It looks like this will test only the year, not all the date fields.
>>> Shouldn't that be s/25/16/ ?
>>> Does this code handle the "true" epoch of 1980-01-01 ?
>> It does now, thanks:
>> This raises the question of what it should do if a day or month is zero
>> but year/month/day are not all zero. Is 1980-0-0 special, or should
>> 1980-0-1 and 1980-1-0 also be tolerated for compatibility with JDK 8?
> As discussed offline, there are no known instances of tools deliberately
> writing zip archives where a day or month is '0' other than 1980-0-0. So
> the current approach seems better than continuing to interpret e.g.
> 1980-1-0 as 1979-12-31 or 1980-0-1 as 1979-12-01.
