You need not reverse the list for counting requests per second. If the data is in sorted order, you can start with any direction. Take the first as the base and keep separating untill you get 1 second or X units like 1000 milliseconds if your data is in milliseconds. The count would be an item of the list and now your base changes to timestamp where you ended.
But looking at the little data you provided it seems it is not sorted. If it is not sorted, one quick solution you can try is like binary search tree, where each node counts the no-requests-from-T-to-T+1 BST would be useful if the data is sparse like a lot of time server is not used and then used continuously. Otherwise instead of bst, you can store the info in array too, faster access time.
