----------------------------------------
Summary: ZipArchiveOutputStream should use last modification time
(mtime) of ZipEntry
Key: COMPRESS-617
URL: https://issues.apache.org/jira/browse/COMPRESS-617
Project: Commons Compress
Issue Type: Task
Components: Archivers
Affects Versions: 1.21
Reporter: Jorge Solórzano
ZipArchiveOutputStream is a reimplementation of java.util.zip.ZipOutputStream,
but since Java 8+ java.util.zip.ZipOutputStream supports setting extended
timestamp fields in optional extra data in UTC time which
ZipArchiveOutputStream do not use:
??When output to a ZIP file or ZIP file formatted output stream the last
modification time set by this method will be stored into zip file entry's date
and time fields in standard MS-DOS date and time format), and the extended
timestamp fields in optional extra data in UTC time.??
https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/zip/ZipEntry.html#setLastModifiedTime(java.nio.file.attribute.FileTime)
As such the reimplementation of ZipArchiveOutputStream should try to follow as
close as possible the behavior of java.util.zip.ZipOutputStream.
So if I setLastModifiedTime(FileTime) in a ZipEntry, that time should add the
extended timestamp fields in the ZipArchiveOutputStream.
