You can use binary search, so this is only O(log N).

You could also take a look at commits 2019-04-02T20:49:36Z!address@hidden 
(9624f609493da7c08016ba00d6895bad0fe26a0e) and the flurry of commits near 
2019-04-14T02:41:31!address@hidden 
(5d8b0fadeec373cd2861328aeb1cb4293cbc9ded) as they seem relevant. But for this 
sort of thing I've found binary search is often best.
