FR: Last Indexed time could have the ISO8601 as a title and show the browser's TZ

[mdaniel]

Currently it shows Last Indexed = 2024-10-05T16:35:43.695Z which places the burden upon the user to know their Zulu offset

As an alternative, it could still preserve that Zulu TS but choose to render the TS according to the browser's timezone, e.g.

<span title="2024-10-05T16:35:43.695Z">Sat Oct 05 2024 09:35:43 GMT-0700</span>
<!-- new Date(Date.parse('2024-10-05T16:35:43.695Z')) -->
