--- Begin Message ---Package: zip Version: 2.20-2 Hello, when running zip -X, the file times are not stripped, contrary to the man page. Also, running zip -A doesn't yield a file that is identified as an MS-DOS executable afterwards. I think this is what the program should do, and also what the man page suggests, since it makes no sense to make room for a program and then not including it. I had to resort to NT to create a self-extracting archive, and it still had it's times in :( Best Regards, --Toni++ -- System Information Debian Release: potato Kernel Version: Linux oak 2.0.38 #6 Sat Dec 4 16:31:11 CET 1999 i686 unknown Versions of the packages zip depends on: ii libc6 2.1.3-13 GNU C Library: Shared libraries and Timezone

--- Begin Message ---Hello. I have finally an official reply from one of the authors (in Cc), which I'll reproduce below. Thanks. Paul Marquess <paul.marqu...@outlook.com> writes: --------------------------------------------------------------- I suspect there is confusion here about the optional extended date/time field and the mandatory DOS date time that MUST be present in every zip file. It is possible to exclude the extended attribute, but the DOS data time cannot be excluded (it can be set to zero, but it has to be present). The key point about the 2.3 documentation for -X is where it says "Do not save extra file attributes". The standard date/time is not an extended attribute. Just to double check this is what I get with a vanilla zip 2.32 Create two zip files, one with standard options, the other using the -X option. $ zip /tmp/23.zip deflate.c $ zip -X /tmp/23x.zip deflate.c Looking inside the standard zip file, 23.zip you can see the presence of the 'UT: Extended Timestamp' field and the standard DOS date time field (Last Mod Time 3275050F 'Mon Mar 21 00:40:30 2005'). $ zipdetails -v /tmp/23.zip 0000 0004 50 4B 03 04 LOCAL HEADER #1 04034B50 0004 0001 14 Extract Zip Spec 14 '2.0' 0005 0001 00 Extract OS 00 'MS-DOS' 0006 0002 00 00 General Purpose Flag 0000 [Bits 1-2] 0 'Normal Compression' 0008 0002 08 00 Compression Method 0008 'Deflated' 000A 0004 0F 05 75 32 Last Mod Time 3275050F 'Mon Mar 21 00:40:30 2005' 000E 0004 C1 3C 82 87 CRC 87823CC1 0012 0004 96 26 00 00 Compressed Length 00002696 0016 0004 E0 85 00 00 Uncompressed Length 000085E0 001A 0002 09 00 Filename Length 0009 001C 0002 1C 00 Extra Length 001C 001E 0009 64 65 66 6C Filename 'deflate.c' 61 74 65 2E 63 0027 0002 55 54 Extra ID #0001 5455 'UT: Extended Timestamp' 0029 0002 09 00 Length 0009 002B 0001 03 Flags '03 mod access' 002C 0004 FE 17 3E 42 Mod Time 423E17FE 'Mon Mar 21 00:40:30 2005' 0030 0004 FE 17 3E 42 Access Time 423E17FE 'Mon Mar 21 00:40:30 2005' 0034 0002 75 78 Extra ID #0002 7875 'ux: Unix Extra Type 3' 0036 0002 0B 00 Length 000B 0038 0001 01 Version 01 0039 0001 04 UID Size 04 003A 0004 EA 03 00 00 UID 000003EA 003E 0001 04 GID Size 04 003F 0004 EA 03 00 00 GID 000003EA 0043 2696 ...
