OpenTime做最称心的C++开发时间库
程序开发频繁涉及时间处理，有一个好用的时间库可以大幅提高工作效率。
OpenTime是最简单易用的C++处理时间工具。
https://github.com/OpenMiniServer
跨平台支持
Windows、linux、Mac、iOS、Android等跨平台设计
编译和执行
请安装cmake工具，用cmake可以构建出VS或者XCode工程，就可以在vs或者xcode上编译运行。
源代码：https://github.com/OpenMiniServer/opentime
git clone https://github.com/OpenMiniServer/opentime
cd ./opentime
mkdir build
cd build
cmake ..
#如果是win32，在该目录出现opentime.sln，点击它就可以启动vs写代码调试
make
./test全部源文件
- src/opentime.h
- src/opentime.cpp
1.时间戳转换成字符串
#include <assert.h>
#include <iostream>
#include "opentime.h"
int main()
{
OpenTime openTime(OpenTime::Unixtime());
std::cout << "Current Unixtime:" << openTime.unixtime() << std::endl;
std::cout << "Current Date:" << openTime.toString() << std::endl;
openTime = 1676704738;
assert(openTime.unixtime() == 1676704738);
assert(openTime.wday() == 6);
assert(openTime.toString() == "2023-02-18 15:18:58");
assert(openTime.toGMT() == "Mon, 18 Feb 2023 15:18:58 GMT");
//2023-02-18 13:37:55
openTime = 1676698675;
assert(openTime.toString("") == "2023-02-18 13:37:55");
assert(openTime.toString("_") == "2023_02_18_13_37_55");
//1991-03-18 13:37:55
openTime = 669274675;
assert(openTime.toString("%Y_%M_%D") == "1991_03_18");
//2010-12-18 03:37:55
openTime = 1292614675;
assert(openTime.toString("%Y_%M_%D_%h_%m_%s") == "2010_12_18_03_37_55");
//1972-06-18 13:37:55
openTime = 77693875;
assert(openTime.toString("date:%h:%m:%s %Y/%M/%D%d") == "date:13:37:55 1972/06/18%d");
return 0;
}2.字符串转换成时间戳
#include <assert.h>
#include <iostream>
#include "opentime.h"
int main()
{
OpenTime openTime;
openTime = "2023-02-18 15:18:58";
int64_t thatTime = 1676704738;
assert(openTime.unixtime() == thatTime);
openTime += 3600 * 24 * 2;
assert(openTime.toString() == "2023-02-20 15:18:58");
openTime.fromGMT("Sat, 18 Feb 2023 15:18:58 GMT");
assert(openTime.unixtime() == thatTime);
//2023-02-18 13:37:55
std::string strTime = "2023-02-18 13:37:55";
openTime = strTime;
assert(openTime.unixtime() == 1676698675);
//1991-03-18 00:00:00
strTime = "1991_03_18";
openTime.fromString(strTime, "%Y_%M_%D");
assert(openTime.unixtime() == 669225600);
//2010-12-18 03:37:55
strTime = "2010_12_18_03_37_55";
openTime.fromString(strTime, "%Y_%M_%D_%h_%m_%s");
assert(openTime.unixtime() == 1292614675);
//1972-06-18 13:37:55
strTime = "date:13:37:55 1972/06/18%d";
openTime.fromString(strTime, "date:%h:%m:%s %Y/%M/%D%d");
assert(openTime.unixtime() == 77693875);
int64_t milliTimeStamp = OpenTime::MilliUnixtime();
std::cout << "Current milliTimeStamp:" << OpenTime(milliTimeStamp / 1000).toString(milliTimeStamp % 1000) << std::endl;
return 0;
}3.GMT时间与时间戳转换
#include <assert.h>
#include <iostream>
#include "opentime.h"
int main()
{
OpenTime openTime;
openTime = "2023-02-18 15:18:58";
openTime += 3600 * 24 * 2;
assert(openTime.toString() == "2023-02-20 15:18:58");
int64_t thatTime = openTime.unixtime();
assert(openTime.toGMT() == "Mon, 20 Feb 2023 15:18:58 GMT");
openTime.fromGMT("Mon, 20 Feb 2023 15:18:58 GMT");
assert(openTime.unixtime() == thatTime);
// sleep 1 second
OpenTime::Sleep(1000);
return 0;
}4.整数时间与时间戳转换
#include <assert.h>
#include <iostream>
#include "opentime.h"
int main()
{
OpenTime openTime;
int64_t inttime = 20230218133755;
openTime.fromIntTime(inttime);
assert(openTime.toString() == "2023-02-18 13:37:55");
assert(openTime.toIntTime() == 20230218133755);
return 0;
}5.时间戳按日对齐
#include <assert.h>
#include "opentime.h"
int main()
{
OpenTime openTime;
//2023-02-18 00:00:00
openTime = "2023-02-18 15:18:58";
int64_t alignTime = openTime.alignDayTime();
assert(OpenTime::ToString(alignTime) == "2023-02-18 00:00:00");
alignTime = OpenTime::AlignDayTime(1642490337);
assert(OpenTime::ToString(alignTime) == "2022-01-18 00:00:00");
return 0;
