Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Use case

Every time I search for the time picker in the API docs I end up in the TimePickerDialog docs.

We should link showTimePicker so it can be easier to reach it and mention it can be used directly to show a dialog with a time picker.

Proposal

Mention showTimePicker can be used directly to show a dialog with a time picker.
