Here, we will explore the ins and outs of MySQL DATEDIFF and its practical applications. We will look deeply into its syntax and provide you with real-world examples to showcase how DATEDIFF can be utilized in different scenarios, such as calculating age, tracking project durations, and more.

Background Knowledge
I will explain how to convert a DATETIME (data type) value in Microsoft SQL Server to Unix timestamp and how to convert Unix timestamp to DATETIME. A Unix timestamp is a integer value of seconds since January 1, 1970 at midnight. For further explanation of Unix timestamps refer to Wikiepedia, UnixTimestamp.com or http://unixtimesta.mp/.
Note: This solution only work on dates prior to 2038-01-19 at 3:14:08 AM, where the delta in seconds exceeds the limit of the INT data type (integer is used as the result of DATEDIFF). See source for further details as I have not verified a solution to this problem.
