When you first set up your PC, you are asked to enter the correct time and choose your appropriate time zone. Over the course of time, your PC (or server) can get out of sync with “real world” time.
If you have data and/or applications that rely on accurate timestamps, the above situation is a problem. Your computer provides the time used by your programs. If that time is inaccurate, the data will be as well.
One solution to this problem is to use a program that helps to synchronize your computer’s clock with the standard clock that is maintained by the government. The National Institute of Standards and Technology maintains that atomic clock. You can download software from their site (http://www.nist.gov/pml/div688/grp40/its.cfm) that automatically updates your PC’s clock so that it agrees with the official US time clock.
