Getting precise elapsed time using Java to the Millisecond

十年热恋 提交于 2021-01-28 12:12:55
问题 I've been searching for an answer to my dilemma and have found some useful tips but nothing that addresses my specific question, so I was hoping someone here might be able to help me out. I'm trying to get a precise elapsed time to the millisecond in Java. I'm using System.nanoTime() to get the current time and implementing it in the following code. Mind you, this was code that I used to test it's precision. long startTime = System.nanoTime()/1000000; while (true) { System.out.println((System

问题 How can I format the time elapsed from seconds to hours, mins, seconds? My code: start = time.time() ... do something elapsed = (time.time() - start) Actual Output: 0.232999801636 Desired/Expected output: 00:00:00.23 回答1: If you want to include times like 0.232999801636 as in your input: import time start = time.time() end = time.time() hours, rem = divmod(end-start, 3600) minutes, seconds = divmod(rem, 60) print("{:0>2}:{:0>2}:{:05.2f}".format(int(hours),int(minutes),seconds)) Example: In

问题 I have two Date s. How can I tell the difference between these two dates in days? I have heard of SimpleDateFormat , but I don't know how to use it. I tried this: String fromdate = "Apr 10 2011"; SimpleDateFormat sdf; sdf = new SimpleDateFormat("MMM DD YYYY"); sdf.parse(fromdate); Calendar cal = Calendar.getInstance(); cal.setTime(sdf); I also tried this: String date1 = "APR 11 2011"; String date2 = "JUN 02 2011"; String format = "MMM DD YYYY"; SimpleDateFormat sdf = new SimpleDateFormat

Fastest way to measure elapsed time in Java [duplicate]

问题 This question already has answers here : How do I measure time elapsed in Java? [duplicate] (15 answers) Closed 3 years ago . Everything I've read about currentTimeMillis vs nanoTime seem to only focus on accuracy. If I'm only looking for elapsed time in milliseconds, which one of these should I use if I want the best performance? Seems like currentTimeMillis would be the answer, since I don't need to convert the final answer from ns to ms, but that's from my application's perspective, and

问题 I've searched in the Web but I've only found a way for do it, but in this way it returns in seconds instead of milliseconds. My code is: #include <stdio.h> #include <assert.h> #include <time.h> int main(void) { int solucion; time_t start, stop; clock_t ticks; long count; time(&start); solucion = divisores_it(92000000, 2); time(&stop); printf("Finnished in %f seconds. \n", difftime(stop, start)); return 0; } 回答1: A cross platform way is to use ftime.

Measuring elapsed time with the Time module

荒凉一梦 提交于 2019-11-27 09:57:27
With the Time module in python is it possible to measure elapsed time? If so, how do I do that? I need to do this so that if the cursor has been in a widget for a certain duration an event happens. Vadim Shender start_time = time.time() # your code elapsed_time = time.time() - start_time You can also write simple decorator to simplify measurement of execution time of various functions: import time from functools import wraps PROF_DATA = {} def profile(fn): @wraps(fn) def with_profiling(*args, **kwargs): start_time = time.time() ret = fn(*args, **kwargs) elapsed_time = time.time() - start_time
