Time options in Settings have changed to uppercase AM and PM instead of lowercase

[leecollings]

Not sure exactly when this change has crept in, but it should ideally be reverted as uppercase use of AM and PM isn't considered correct.

All of the sources above state that lowercase use of am and pm should be used.

@leecollings welcome back to Trac.

I might be wrong, but I think you have a plugin installed that is changing core's behavior.

By default, g:i a, g:i A, and H:i are available to be selected and the ​time_formats filter allows the available options to be changed. So, I suspect you have a plugin (or even your theme) installed that is using that filter.

Can you try deactivating all plugins and switching to one of the bundled themes and report back whether you see the g:i a option available?

Hi there @pbiron,

It was a great suggestion, and in my mind I was convinced this must be it. But having deactivated all plugins, and switched back to TwentyTwentyOne, the options in Settings still only show an AM/PM option selected, with my previous am/pm value being in the 'custom' input field.
