In the Field Service Mobile app, changing the date opens a spinner control that allows changing the components of the date. At the bottom of this control are buttons to cancel or accept the change. Changing the time opens another spinner control that allows changing of the components of the time. There are no buttons on the bottom to cancel or accept the change. To accept the change, you must click/touch somewhere off of the time control. Consistent presentation would suggest the same two buttons at the bottom of the time control to cancel or accept the change.
