time out insufficient material

Since black ran out of time, it is a draw because white does not have sufficient material to checkmate. If white had run out of time, he would have lost, since black does have enough material for checkmate.

Notice that in this losing position, if white was left with even just one pawn, he would have won. That one pawn would have been a potential queen, which is sufficient material for checkmate.

"Some of the above situations might be treated slightly differently in FIDE or USCF tournaments, or on other sites.

In the specific case of two knights versus a lone king, USCF rule specifies that the game is drawn because there is no forced mate. The FIDE rule specifies that the game is drawn only when there is no possible mate, and so would not include two knights vs a king as an automatic draw, since it is technically possible to checkmate the king if the king 'helps' you by making specific moves to allow the checkmate. However, Chess.com follows the USCF rule in this case, and calls two knights insufficient mating material because the checkmate can not be forced."
@Sarg0n
The above chess.com link seems to muddy the water somewhat by saying that if you have a king vs. two knights you CAN lose on time. But they then add that you must have another piece.

"-King + two knights exception
Although a king and two knights is considered insufficient mating material for other situations, a timeout against these pieces does not lead to a draw. If your opponent only has a king and two knights, and you run out of time, you will get the loss, not the draw. This is due to a king and two knights being technically possible to checkmate an opponent when they have another piece on the board, even though the mate can't be forced, it is still possible. "
