概述

• 本文演示环境： Windows10
• 使用C语言获取年月日时分秒毫秒，

代码

#include <iostream>
#include <string>
#include <time.h>
#include <sys/timeb.h>
using namespace std;

struct NowDate
{
	char year_month_day_[16] = {0}; //年月日
	char hour_minute_second_[16] = {0}; //时分秒
	char mill_sec_[4] = {0};  //毫秒
};

/// 获取时间
NowDate getTime()
{
	time_t timep;
	time(&timep);
	NowDate date;

	strftime(date.year_month_day_, sizeof(date.year_month_day_), "%Y-%m-%d", localtime(&timep));
	strftime(date.hour_minute_second_, sizeof(date.hour_minute_second_), "%H:%M:%S", localtime(&timep));

	struct timeb tb;
	ftime(&tb);
	sprintf(date.mill_sec_, "%d", tb.millitm);

	return date;
}

int main()
{
	NowDate time = getTime();
	cout << "year-month-day:" << time.year_month_day_ << endl;
	cout << "hour-minute-second" << time.hour_minute_second_ << endl;
	cout << "mill-seconds" << time.mill_sec_ << endl;

	system("pause");
	return 0;
}
