Steps to reproduce

1. Create Reactive Form
2. Add TimePicker with formControlName
3. Set FormGroup data with patchValue, where the input for TimePicker is a string representation of a Date (new Date().toJSON())
4. Click on TimePicker and pick something else.

What is expected?

Should convert the string to the Date

What is actually happening?

Tries to call Date related functions on a string, like getHour, getMinutes which leads to crash.
