   This needs a little more information to be resolved, can you provide a reproducible scenario?

   I faced this issue today.
   In the browser (Firefox), I create a zip:

   const zip = new JSZip();
   const fileContent = await download(fileStatus.fileId); // Uint8Array
   zip.file(filename, fileContent);
   const buffer = await zip.generateAsync({
     compression: "DEFLATE",
     compressionOptions: {level: 9},
     type: "uint8array",
   });

   If I save the zip from buffer on my system and then extract it immediately, I get this:

   -rw-rw-r-- 1 cleyfaye cleyfaye  40827 May 21 08:26 'content.pdf'
   -rw-rw-r-- 1 cleyfaye cleyfaye 607523 May 21 10:26 'generated.zip'
   

   As expected, the zip creation time is correct (it shows 10:26 here); but the extracted file have 08:26. It feels like it's a timezone issue (I'm currently in a UTC+2 timezone).
   This behavior happens across multiple systems: using unzip on a debian system or whatever default zip tools exists on OSX.
