The time complexity for DFS is O (n + m). We get this complexity considering the fact that we are visiting each node only once and in the case of a tree (no cycles) we are crossing all the edges once. For example, if the start node is u, and the end node is v, we are thinking at the worst-case scenario when v will be the last visited node.
