#24 Invalid file date after extracting

my space

Some files compressed under Windows XP pro SP1, when
uncompressed under Solaris has an invalid date
(although the date for "7za l" is correct).
It may be a problem of the 7-Zip file format, but as I
found it using p7zip, I decided to post the bug report
The problem doesn't occur using zip compression.

A 7z archive presenting the problem is attached.

Contact me through the sourceforge messaging system or
the 7-Zip forum if you need more info.

I hope the following information will help.

p7zip compiled on a first machine :
SunOS sun04 5.8 Generic_117350-16 sun4u sparc

gcc version 2.95.2 19991024 (release)
p7zip Version 4.14.01 (locale=fr_CA,Utf16=on,HugeFiles=on)

p7zip executed on second machine :
SunOS malawi 5.8 Generic_108528-29 sun4u sparc

File compressed using :
7-Zip (A) 4.15 beta

    thank you for supporting p7zip.

    This bug arises in "big endian" machine.

    This bug will be fixed in the next version of p7zip.

    Cool, thank you for the quick answer.
    This bug prevents me from using p7zip at work; so, while
    waiting for the next release, I'll switch back to standard
    tools (tar + gzip/bzip2 or zip).
