I use the CTime: : GetCurrentTime () to obtain time; But access is only the time displayed on the computer, the time is not necessarily correct,

How to obtain real time?

I want to do with real time and computer time, determine the computer time is correct

Search the NTP SNTP, network timing protocol

Also, use CTime: : GetCurrentTime (), a % X minutes, when you will get what can separate for hours, minutes and seconds

Every time you can take time before the synchronization
Call w32tm/resync command Windows's own time synchronization
