CircularTimePicker
Picking a time can be tough without context. A BitCircularTimePicker offers a drop-down control that’s optimized for picking a single time from a clock view where contextual information like the day of the week or fullness of the calendar is important. You can modify the calendar to provide additional context or to limit available times.

Value format
Applications can customize how dates are formatted and parsed. Formatted dates can be ambiguous, so the control will avoid parsing the formatted strings of dates selected using the UI when text input is allowed.
In this example, we are formatting and parsing times as hh-mm.ss.
