The timezone in the `last-modified` header is specified incorrectly.

[phi-friday]

Description

The date uses utc, but the calculated time was entered correctly.
However, last-modified is the correct time, but the timezone is specified as utc.
The same goes for the if-modified-since header in request.
The current time is 2024-08-28T04:24:31.699596+00:00,
so the last modified time of Wed, 28 Aug 2024 13:08:50 GMT is obviously wrong.
