DateTime Helper Class for C#

First, the original intention of the DateTime helper class

In the project development of C#, we often encounter the problem of time conversion, or calculate the difference between two times. It will be very troublesome to re-implement each time, and the implementation methods of each developer are also inconsistent.There are too many references and it is not easy to maintain. This DateTime helper class encapsulates the common operations of time.

Second, the function of the DateTime helper class

* Function:
* 1. Get the difference in days
* 2. Get the difference in hours
* 3. Get the difference in minutes
* 4. Get the difference in seconds
*5. Others (format conversion, cutting year, month, day, hour, minute, second)
