I have component for handling date + time: [https://stackblitz.com/edit/stackblitz-starters-b3wdcj]

When I change year/month/day manually in input (not in picker) , some events are fired (dateInput, ngModelChange). But when I change hours/minutes manually in matInput (just change 12 -> 13), nothing happens.
Is it possible to handle time change somehow?

I do not want to handle/set time in picker, but need to handle time change in matInput.

Thanks a lot for any advice.
