Subject Re: X5455_ExtendedTimestamp support in zip/jar ?
Date Sat, 11 Oct 2014 06:21:46 GMT
from the spec,
this is a Unix extra field, which has an equivalent NTFS extra field with 
timestamp: I didn't see any other case of such timestamp extra-info

IMHO, if we add such extra fields, we should try to be consistent across these
