time

问题 I need to custom format dates. In ruby, I would use strftime, or string formatted time, to accomplish this. now = Time.new now.strftime '%a, %d of %b' #=> "Sat, 27 of Jun" Does javascript use strftime or some equivalent? How can I get a similar effect in javascript? 回答1: UPDATE Arguments of toLocaleString method can also configure the format of the dates. This is supported in modern browser versions, you can see more information here. let date = new Date(Date.UTC(2015, 5, 27, 12, 0, 0)) ,

问题 In the following program, I have tried to measure the execution time of a job(for loop). Most of the time it works fine, however, sometimes, it returns negative values!! My first guess is that the variable may get overflowed. Can anyone please let me whether I am right or not? How can I solve the problem? Thanks int main(int argc, char **argv) { long int ST; long int ET; struct timespec gettime_now; clock_gettime(CLOCK_REALTIME, &gettime_now); ST= gettime_now.tv_nsec; for (i=0; i < 1000; i++)

问题 Is there a standard implementation to print std::duration as a human readable duration? steady_clock::time_point start = steady_clock::now(); doSomeFoo(); steady_clock::time_point end = steady_clock::now(); std::cout << "Operation took " << may_be_std::theMagic(start-end) << std::endl; Which should print something similar to: "Operation took 10d:15h:12m:14:s" or something similar. 回答1: Agreed there is no standard implementation. Here is how you can write one yourself: #include <iostream>

What I got instead: Exception in thread "main" java.time.format
