The time interval for obtaining SQL server DateTime is not 1 ms, the time interval is 3.33 ms, and 3.33 ms C # development,

The time interval for obtaining DateTime in SQL server is 3.33 milliseconds (3.33 ms). Therefore, if the value is increased by 1 millisecond, the default time of the database is not increased.

C # Development

DateTime dt = new DateTime ();

Dt = DateTime. Now;
Dt = dt. AddMilliseconds (1); // The value of dt does not change in the database. The time difference is 1 millisecond, and the default time of sqlserver does not increase.

Dt = dt. AddMilliseconds (3); // the time difference between 3 ms and 3 ms for the value of dt in the database is increased.
