Linux获取当前年月日后缀精确到微秒,例如2017-05-06T23:57:07.713171

代码如下：详细见注释

#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 );//获取当前时间，该结构体返回Unix时间戳秒数与微秒数local_time = localtime(&start.tv_sec);//将秒转换标准时间strftime(str_time, sizeof(str_time), "%Y-%m-%dT%H:%M:%S", local_time);sprintf(ms,".%ld",start.tv_usec);strcat(str_time,ms);//将毫秒附着在时间后printf("time: %s \n", str_time);return 0;
}
