If you’re using a Twitter client such as HootSuite, you can easily see the exact time that a tweet in your feed was posted, as HootSuite conveniently displays the timestamp above the message. Other clients work in a similar way. On Twitter.com things are a little different. There, Twitter prefers to show you how long it was since a tweet was posted. For example, it might say 55 seconds ago, 19 minutes ago, or 1 or more hours ago.
