While uploading file one by one to AWS S3 bucket using Java code, I'm observing a strange issue with Last Modified Date column, all the files are showing same last modified date. I followed few posted in StackOverFlow but no-where is properly mentioned on how to set user defied meta-data while storing file to S3.

I did like this in my code but didn't not work for me. Could you please suggest?

ObjectMetadata metaData = new ObjectMetadata();
metaData.setContentLength(bytes.length);
metaData.setHeader("x-amz-meta-last-modified", OffsetDateTime.parse(new Date().toString()).toLocalDate());

`OffsetDateTime.parse(new Date().toString())` will never work. Just use `LocalDate.now(ZoneId.systemDefault())`. – Ole V.V. Mar 16 '21 at 10:56
I think the datetime format should be like: 2011-10-15T16:25:49.000Z else it won't be reflected. – Surajit Sarkar Mar 16 '21 at 11:08
if you have implemented the same, could you please guide me on how you have set "x-amz-meta-last-modified" in header? – Surajit Sarkar Mar 16 '21 at 17:03
