What's the impact on SEO from having an 'Estimated read time' in the SERP?

Early this year we noticed Google was scraping the ‘Estimated read time’ from some blog post pages into their meta descriptions.

We ran a title tag test with a customer in the listings space on their search results pages. Our customer had the current month and year in the title tag to indicate freshness, but actually updates their listings more frequently than once a month - they update them daily. We wanted to test if putting “Updated Daily” instead would improve organic traffic.
