My program is a real-time system time into database, but why I checked the, found that after time was advanced in the back of the library, should be in the library in front of him was delayed by several seconds into the library, the last is not short, although the data in the database but it's too strange, I are according to the real-time system time deposit, time delay for so long that point in time, but also can save? How did this happen?

the database query you the time of the current program is available with you, you use the database GetDate time

Need to see your database data sorting, etc., and if there is a order insert

Network latency can also cause the illusion of time back or time is not synchronized,
