Description of the issue:
HTML 5 input types date, datetime-local and time do not use system configured date formatting and time formatting.
On my Fedora 41 environment
Steps to Reproduce (add as many as necessary): 1. 2. 3.
Visit https://jsfiddle.net/8p9o04L2/2/ which has the following HTML:
<input type="date" value="2024-12-31">
<input type="datetime-local" value="2025-12-31 16:24">
<input type="time" value="16:24">
Note, by default my browser language is set to en-US but for testing I had it only set to nl-NL and same happens.
However, browser LANGUAGE shouldn’t be deciding the formatting for numbers, date and time.
Actual Result (gifs and screenshots are welcome!):
This shows the following on my system:
Expected result:
My system is set to the Dutch culture so would use the following 24 hour datetime format:
DD-MM-YYYY HH:mm
31-12-2024 16:35
So, not in the the format MM/DD/YYYY hh:mm PM/AM
