You’ll find one in http://commons.apache.org/lang/ It’s called org.apache.commons.lang.time.StopWatch But it roughly does the same as yours. If you’re in for more precision, use System.nanoTime() See also this question here: Time measuring overhead in Java
You can readily do this this with the input format U.u. $now = DateTime::createFromFormat(‘U.u’, microtime(true)); echo $now->format(“m-d-Y H:i:s.u”); This produces the following output: 04-13-2015 05:56:22.082300 From the PHP manual page for date formats: U = Seconds since the Unix Epoch u = Microseconds http://php.net/manual/en/function.date.php Thanks goes to giggsey for pointing out a flaw in my … Read more
long milliseconds = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond; This is actually how the various Unix conversion methods are implemented in the DateTimeOffset class (.NET Framework 4.6+, .NET Standard 1.3+): long milliseconds = DateTimeOffset.Now.ToUnixTimeMilliseconds();
How can I exactly construct a time stamp of actual time with milliseconds precision? I suspect you mean millisecond accuracy. DateTime has a lot of precision, but is fairly coarse in terms of accuracy. Generally speaking, you can’t. Usually the system clock (which is where DateTime.Now gets its data from) has a resolution of around … Read more
To get a date string with milliseconds, use [:-3] to trim the last three digits of %f (microseconds): >>> from datetime import datetime >>> datetime.utcnow().strftime(‘%Y-%m-%d %H:%M:%S.%f’)[:-3] ‘2022-09-24 10:18:32.926’ Or slightly shorter: >>> from datetime import datetime >>> datetime.utcnow().strftime(‘%F %T.%f’)[:-3]
The short answer is: $milliseconds = floor(microtime(true) * 1000);
I’m not entirely sure what you mean by “current milliseconds” but I’ll assume it’s the number of milliseconds since the “epoch,” namely midnight, January 1, 1970 UTC. If you want to find the number of milliseconds since the epoch right now, then use System.currentTimeMillis() as Anubian Noob has pointed out. If so, there’s no reason … Read more
