Content Published date and last modification date is really tending to SEO ranking?
We know – Google shows date on the Google snippet (SERP). Google may show published date or updated date in the snippet. It depends on Google. You can also show time with date if possible. Google also see this but use right time zone.

Published Date = Original Date
Updated Date = Last Modification Date

People may use fake date for both cases (publish & Updated), and may be show fake date on the snippet. How google handle this?
Google crawl webpages on the regular basis and publish / updated date can be analyzed by google itself by comparing content.
Although, I have not seen any penalty for fake date, But Gary said that Google is working on it and may take strict action in future.

What is the Difference between lastmod Date in XML sitemap and web page?
Why we need to add last modification date on the webpage while using this date in xml sitemap.
Google said on this question that sitemap lastmod for whole page (body + head) changes, on the other hand page lastmod for page content changes.
What Will Happen If Published Date Same for Multiple Pages
Many people do this. They write content in bulk and publish them on same time. This is a bad SEO practice. We should add content one by one and should take minimum 1-2 days gap for publishing.
If you don’t have consistency of posting or post too many pages on the same day – in that case – Google think that content is auto-generated or not a manual content and written by a real Author/writer. If you regularly post too many pages through multiple authors then it is fine.
If you have already posted multiple pages on same date then better to remove dates from the page. Google will pick date when it will crawl for their other ranking analysis. (not for snippet)
