No material to mate

Why is time still going when both players only have a king and bishop? In my last game ( I lost on time but both palyers have no material to mate?

If the bishops had been on the same color, it would be a draw. As it is, there is a possible checkmate on the board, and black did not leave themselves enough time to prove they could avoid it.
