What will be the time complexity of the following nested loop:

for(int i=2;i<n;++i){
    for(int j=i;j<n;j+=i){
        //some code here
    }
}

Actually I was participating in a competition on Codechef last night. And there was a question for which I thought of a solution like this. But the range of n was [2, 10⁶] and time limit was 1.5s. So I thought that my solution will exceed the time limit and hence I didn't submit it. But after the contest I saw another guy submitting the same solution and getting his solution accepted. So, can someone tell what is the exact time complexity of this code snippet?
