Check time difference in Javascript
...diff = date2 - date1;
// 28800000 milliseconds (8 hours)
You can then convert milliseconds to hour, minute and seconds like this:
var msec = diff;
var hh = Math.floor(msec / 1000 / 60 / 60);
msec -= hh * 1000 * 60 * 60;
var mm = Math.floor(msec / 1000 / 60);
msec -= mm * 1000 * 60;
var ss = Ma...

How to use clock() in C++
...
@Th.Thielemann both clock() and clock_t are from the C Standard Library's header of time.h, and therefore do not need the use of std namespace prefixes after the inclusion of their libraries. <ctime> wraps that value and function with the std name...
