Some files add to zip from disk create bug. May be some file, with change time 1979 (or 1917?), when create time is 2019. And sometime work correctly. I cant find more, because write 0 errors. No write error in addFile phase, no write error in $zip->close. Write only warning with "No Error" text.
I have min 1 file, but, i replace it from older program, not save for testing, sorry. image jpeg from adobe ilustrator, logo EU project.
I test, do file by file to found problem file (50%, 25%, 12,5%...). When i replace, archive is created by zip-close.
I this file may be created from word document, save image from  doc to file. Or extract by Far / Rar from xdocfile. Or somebody sand me by mail for project.
Workable file have info
