Public bug reported:
Description of problem:
Unzip will sometimes round up timestamps of unpacked files. This
results in a 1-second difference between the timestamp shown via zipinfo
-T, and the unzipped file on disk
Steps to Reproduce:
1. Zip files with different timestamps.
2. Note the timestamps stored in the archive with `zipinfo -T`
3. Unzip the archive
4. Compare the timestamps with `ls --full-time`
5. Note a difference of 1 second on some files.
Actual results:
Timestamps are off by a second on some files
Expected results:
Timestamps should match between zipinfo and ls.
Example -- note the timestamps on file "2"

Description: Archiver for .zip files
This is InfoZIP's zip program. It produces files that are fully
compatible with the popular PKZIP program; however, the command line
options are not identical. In other words, the end result is the same,
but the methods differ. :-)

This version supports encryption.

Description: De-archiver for .zip files
InfoZIP's unzip program. With the exception of multi-volume archives
(ie, .ZIP files that are split across several disks using PKZIP's /& option),
this can handle any file produced either by PKZIP, or the corresponding
InfoZIP zip program.
