Linux獲取當前年月日后綴精確到微秒,例如2017-05-06T23:57:07.713171

代碼如下：詳細見注釋

#include <stdio.h>
#include <string.h>
#include <time.h>
#include <sys/time.h>int main() {struct timeval start;struct tm *local_time = NULL;static char str_time[100];char ms[16];gettimeofday( &start, NULL );//獲取當前時間，該結構體返回Unix時間戳秒數與微秒數local_time = localtime(&start.tv_sec);//將秒轉換標準時間strftime(str_time, sizeof(str_time), "%Y-%m-%dT%H:%M:%S", local_time);sprintf(ms,".%ld",start.tv_usec);strcat(str_time,ms);//將毫秒附著在時間后printf("time: %s \n", str_time);return 0;
}
