Description
When typing hour, time picker selects 0h option when typing hour > 9h.
There is a time parsing issue with dateFnsAdapter.
Reproduction
StackBlitz link: https://stackblitz.com/edit/bmbh8m2b-gpqc3u8f?file=src%2Fexample%2Ftimepicker-locale-example.ts
Steps to reproduce:
- Wait a bit for app to load, as it is super slow. (Try to use chrome instead of firefox if it never loads 🥲 ).
- App is ready when the input is displayed.
- Type any 1-digit => it works
- Type 10, or anything up to 23 => it selects 0 (??)
Expected Behavior
Type 10, or anything up to 23 => it selects matching option.
We should be able to customize hour parser with MatDateFormats, as for dates.
Actual Behavior
Type 10, or anything up to 23 => it selects 0h option.
We are not able to customize hour parser with MatDateFormats: only typing 0 to 9 hours, or typing full hours and minutes (HH:mm) work.
Environment
- Angular: 20.2.4 (same behavior on 19)
- CDK/Material: 20.2.4
