Sentry Crash Report:

Description Roke Julian Lockhart Beedell 2023-11-19 01:39:33 UTC 
SUMMARY
Use UTC offset to indicate the time zone (per ISO 8601) rather than non-standard 3-letter codes (they don't even conform to https://www.iana.org/time-zones so they're not particularly useful).

STEPS TO REPRODUCE
1. `%Y%M%DT%H%m%S%t`

OBSERVED RESULT
20231026T030735BST (non-standard)

EXPECTED RESULT
20231026T030735+0100 (per ISO 8601)

Comment 1 Noah Davis 2023-11-29 08:26:34 UTC 
I think it would be good to have both, if possible. After looking at https://en.wikipedia.org/wiki/List_of_time_zone_abbreviations, they definitely are problematic though.

Support all QDateTime string formatting options as filename placeholders

There are a lot of them and showing them all in the UI might be too
much, so they're currently hidden features. I know adding hidden
features is kind of dubious, but I don't think it'll be harmful. We
can't add new translatable strings right now without asking for a string
freeze exception anyway.

See QDate and QTime docs:

In 24.02, you can use `<tt>` as a placeholder for ±HHmm or `<ttt>` for ±HH:mm

Extra date/time placeholder descriptions, 12 hour <h>/<hh>

Now you can see extra date/time placeholders with descriptions in the
configuration dialog with the "Show More" link button.

Moves "AM/PM or am/pm (localized)", "Hour (00–23)" and "Timezone offset
(±0000)" to main list.

Moves "Timezone (abbreviation)" to extras since timezone codes are not
standardized or unique.

`<h>` and `<hh>` are now always 12 hour format so that they can be
meaningfully different from `<H>` and `<HH>`.

Updated filename test for `<h>` and `<hh>`.
