cocos2d-x 中c++ lua js获取前后时间差毫秒级别代码

c++:
double millisecondNow() {
struct timeval tv;
gettimeofday(&tv, nullptr);
log("CurrentTime MillSecond %f", (double)tv.tv_sec * 1000 + (double)tv.tv_usec / 1000);
return (double)tv.tv_sec * 1000 + (double)tv.tv_usec / 1000;
}
auto milliS1=millisecondNow();
CCLOG ("milliS1: %f \n",milliS1);
for( int i = 0; i < 100000000; i ++ )
{
}
auto milliS2=millisecondNow();
CCLOG ("milliS2: %f \n",milliS2);
CCLOG ("消耗秒: %f \n",(milliS2-milliS1)/1000);
js:
var time1 = Date.now();
cc.log("time1:" + time1);
for (var i = 0, lenI = 100000000; i < lenI; i++) {
}
var time2 = Date.now();
cc.log("time2:" + Date.now());
cc.log("use time:" + ((time2 - time1)/1000)+"s");
lua:
local socket = require "socket"
local t0 = socket.gettime()
-- do something
for i=1,100000000 do
end
local t1 = socket.gettime()
print("used time: "..t1)
print("used time: "..t0)
print("used time: "..t1-t0.."s")
