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.

registered with the VSP but missed their votes. Clicking on the ticket
hash redirects to the Ticket Search tab with the details of the missed
ticket displayed.
