Subject: Fix FILETIME truncation on `archive_write_finish_entry()` on Windows (#2050)
X-Git-Tag: v3.7.3~26
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=010a2af130923cf616b5d5e094c25101479509b1;p=thirdparty%2Flibarchive.git

Fix FILETIME truncation on `archive_write_finish_entry()` on Windows (#2050)

On Windows, `archive_write_finish_entry()` does not restore time
correctly.
It truncates the last digit of original FILETIME which is stored in the
archive.
This commit fixes this behavior.
See libarchive#2049 for detailed explanation on this issue.
