Using a relative time rather than absolute requires far less effort for a reader to understand, e.g. compare "25 Oct 2024 11:12:49 UTC" to "3 minutes ago". As a nice side-effect this also fixes a minor privacy issue where using the full absolute timestamp would expose the server timezone to the public.
