How to find the exact time of tweets

The Twitter API returns UTC time of the tweet [1] while we see the tweet in our timeline in our local time (in my case, UTC+1). The original time of the tweet published by the author should be UTC time - utc_offset/3600 = 00:14:52 - 7hours = 17:14:52 on Thursday April [2, 3].
