1. The return unit is milliseconds. # Include DWORD dwstart = gettickcount ();// Test code DWORD dwtime = gettickcount ()-dwstart; Note: gettickcount () has a limited precision, which is related to the CPU. Generally, the accuracy is around 16 ms,

From erlang time functions to the time correction system, erlang correctionMany people will notice this problem. erlang provides two time functions, erlang: now () and OS: timestamp (). In the same usage, the current time is returned. The specific

How can we delay your program by 1 ms, 2 Ms ...... I used the timer () function for a long time when I used vbprogramming. However, after careful analysis, we will find that the timer () function has a very low precision, and the precision can only

How can we get the system time in microseconds? Gracian (Mylee) 15:08:30 on C/C ++/ C LanguageQuestion? Number of questions: 20. replies: 6 On the first floor, chillman (the talented old man) replied to 15:16:59, with a score of 8. The number of

  Note: When performing some performance tests, we sometimes want to calculateProgramSometimes, you may write a shell script to control the performance test (for example, you want to run n times to obtain the average value). In short, one of these
