1756211 - Time input using 24h does not change AM/PM

Status: RESOLVED FIXED

(Core :: Layout: Form Controls, enhancement)

Steps to reproduce:

I have an <input type="time" value="01:00" /> field and my system is set to 12h time. The input displays "01:00 AM", as expected. If I type "16" into the hours field, it correctly updates to "04" (since 4pm is the equivalent of 16:00), but the meridiem remains at AM.

User Agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:97.0) Gecko/20100101 Firefox/97.0"

Actual results:

I typed "16" into the hours field and the resulting display is "04:00 AM". It got the hour conversion right, but not the meridiem.

Expected results:

The meridiem should update to PM. Typing "16" into the hours field should result in a display of "04:00 PM".

Note: I wouldn't expect the reverse to happen. If the field is "02:00 PM" and I type "5", it shouldn't become 5am. But typing an hour value greater than 12 should trigger a meridiem shift.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Layout: Form Controls' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

This is the relevant code: https://searchfox.org/mozilla-central/rev/a7d4b256719357f3f5cf89b30285d8a53f4e5d98/toolkit/content/widgets/datetimebox.js#1184-1197

That should presumably also call this.setDayPeriodValue(this.mPMIndicator).

I was made aware that bugs are auto-assigned once a patch is submitted, and it is not usually required to ask to be assigned to one. I will submit a proposed patch for this. I look forward to feedback on the code. Thanks.
