import time def main(): start = time.perf_counter() time.sleep(0.3) # in seconds, i.e. 300 milliseconds # Calculate duration and convert to milliseconds elapsed_ms = (time.perf_counter() - start) * 1000 print(f"Elapsed time: {elapsed_ms:.2f} ms") """ Elapsed time: 300.13 ms """	import std.stdio; import core.thread; // MonoTime, Thread void main() { auto start = MonoTime.currTime; Thread.sleep(300.msecs); auto duration = MonoTime.currTime - start; writeln("Elapsed time: ", duration.total!"msecs", " ms"); /* Elapsed time: 300 ms */ }

Output in various units:

writeln("Elapsed time:");
writeln("  ", duration.total!"nsecs", " nanoseconds");
writeln("  ", duration.total!"usecs", " microseconds");
writeln("  ", duration.total!"msecs", " milliseconds");
writeln("  ", duration.total!"seconds", " seconds");

Elapsed time:
