http://en.lichess.org/m1Hl0Sa0I got draw on time out. Is it correct? I don't understand.
If it is correct can you explain to me why there a draw?
I'm guessing it's a draw because there's not enough material to checkmate with.
You'll find an answer here:

"A draw may also occur when one side wins on time, but has insufficient material to mate."
Insufficient mating material.
that's probably why he sacrificed his rook for your pawn
If you have not enough material to win the game (e.g. only the king and the bishop), and your opponent has enough material to win the game, but he or she runs out of time, it is a draw, not the win for you.
Now it seems I realized.
Thanks for answers, especially #3 link to lichess/qa.
This can be abused, for instance if you only have a minor piece but have a forced mate next move, the opponent can decide to "lose" on time, but gets a draw by "insufficient mating material". But all systems to claim late-game draws have corner cases. Minor vs minor without an immediate mate was a draw in Browne's 1990s blitz league, but in some women's championship playoff a few years back an 5-minute armaggdeon game ended with a flag falling (no increment!) in knight vs knight with both kings near the center of the board but since mate was "constructable" it was declared a win.
I hate that the rules about this situation are not the same everywhere and in every time control. From what I've seen online and completely fine with, is that one minor piece is always insufficient to mate. Although there actually are "constructable mates", as was pointed out in #7. But the point is that the opponent HAS to let that position happen, he has to help mate himself; and only a tiny tiny chance this could be forced is in some very incredible position, which I can't even imagine. People have to get down to Earth and dismiss that tiniest probability of happening and always assume it as a draw. Another example: most people are fine with the 50-move rule, but we all know due to endgame tablebase there are endings, which are forced mates in more than 50 moves. To be honest, I doubt that any player, even top grandmasters, could reproduce those ultra complicated, illogical lines. (judging even by how hard it can be for a grandmaster to checkmate with a knight and a bishop, which is actually a basic thing)
That was my humble opinon. :)
