How to convert `System.currentTimeMillis();` to seconds?

    long start6=System.currentTimeMillis();
    System.out.println(counter.countPrimes(100000000)+&quot; for &quot;+start6);

The console shows me `5761455 for 1307816001290`.
I can&#39;t read how many seconds that is.

Any help?

How to measure the a time-span in seconds using System.currentTimeMillis()?

In my thread (using boost::thread) I need to retrieve the current time in ms or less and to convert into ms:

Actually, reading here I&#39;ve found this:

    tick = boost::posix_time::second_clock::local_time();
    now  = boost::posix_time::second_clock::local_time();

And seems to work, but after I need to have a long value of the milliseconds of the now...

How can I do it?


Get current time in milliseconds using C++ and Boost

I am trying to convert milliseconds to a date using the javascript using:
    
    new Date(Milliseconds); 

constructor, but when I give it a milliseconds value of say 1372439683000 it returns invalid date. If I go to a [site that converts milliseconds to date][1] it returns the correct date.

Any ideas why?

new Date(milliseconds) returns Invalid date

How can I exactly construct a time stamp of actual time with milliseconds precision? 

I need something like 16.4.2013 9:48:00:123. Is this possible? I have an application, where I sample values 10 times per second, and I need to show them in a graph.


Get DateTime.Now with milliseconds precision

How can I format a [`datetime`](https://docs.python.org/3/library/datetime.html#datetime-objects) object as a string with milliseconds?

Format a datetime into a string with milliseconds

I&#39;m making a program in which I need to get the time in milliseconds. By time, I mean a number that is never equal to itself, and is always 1000 numbers bigger than it was a second ago. I&#39;ve tried converting `DateTime.Now` to a `TimeSpan` and getting the `TotalMilliseconds` from that... but I&#39;ve heard it isn&#39;t perfectly accurate.

Is there an easier way to do this?


Get time in milliseconds using C#

I am trying to get a formatted date, including the microseconds from a UNIX timestamp specified in milliseconds.

The only problem is I keep getting 000000, e.g.

    $milliseconds = 1375010774123;
    $d = date(&quot;m-d-Y H:i:s.u&quot;, $milliseconds/1000);
    print $d;

Getting date format m-d-Y H:i:s.u from milliseconds

Note, I do NOT want millis from epoch. I want the number of milliseconds currently on the clock.

So for example, I have this bit of code.

    Date date2 = new Date(); 
    Long time2 = (long) (((((date2.getHours() * 60) + date2.getMinutes())* 60 ) + date2.getSeconds()) * 1000);
		
Is there a way to get milliseconds with date?
Is there another way to do this?

**Note:** `System.currentTimeMillis()` gives me millis from epoch which is not what I&#39;m looking for.

How can I get the count of milliseconds since midnight for the current?

Is there a stopwatch in Java?  
On Google I only found code of stopwatches that don&#39;t work - they always return 0 milliseconds.

This code I found doesn&#39;t work and I don&#39;t see why.

    public class StopWatch {
      
      private long startTime = 0;
      private long stopTime = 0;
      private boolean running = false;
      
      
      public void start() {
        this.startTime = System.currentTimeMillis();
        this.running = true;
      }
      
      
      public void stop() {
        this.stopTime = System.currentTimeMillis();
        this.running = false;
      }
      
      
      //elaspsed time in milliseconds
      public long getElapsedTime() {
        long elapsed;
        if (running) {
          elapsed = (System.currentTimeMillis() - startTime);
        } else {
          elapsed = (stopTime - startTime);
        }
        return elapsed;
      }
      
      
      //elaspsed time in seconds
      public long getElapsedTimeSecs() {
        long elapsed;
        if (running) {
          elapsed = ((System.currentTimeMillis() - startTime) / 1000);
        } else {
          elapsed = ((stopTime - startTime) / 1000);
        }
        return elapsed;
      }
    }


Is there a stopwatch in Java?

I have a time as a number of milliseconds and I want to convert it to a `HH:MM:SS` format. It should wrap around, with `milliseconds = 86400000` I want to get `00:00:00`.

How to convert time in milliseconds to hours, min, sec format in JavaScript?

I need the exact duration of LENGTH_LONG and LENGTH_SHORT in milliseconds (ms). Also I need to know if the duration of Toast message with LENGTH_LONG will have the same duration in any phone and with any API version.

Does someone know where is the duration defined ?, I mean defined in ms . I know that LENGTH_LONG is some int const with value 1. But I could not find where is the actual duration defined.

I have to develop a application using MySQL and I have to save values like &quot;1412792828893&quot; which represent a timestamp but with a precision of a millisecond. That is, the amount of milliseconds since 1.1.1970. I declare the row as &lt;code&gt;timestamp&lt;/code&gt; but unfortunately this didn&#39;t work. All values are set to &lt;code&gt;0000-00-00 00:00:00&lt;/code&gt;

    CREATE TABLE IF NOT EXISTS `probability` (
    `id` int(11) NOT NULL AUTO_INCREMENT,
    `segment_id` int(11) NOT NULL,
    `probability` float NOT NULL,
    `measured_at` timestamp NOT NULL,
    `provider_id` int(11) NOT NULL,
    PRIMARY KEY (`id`)
    ) ;

How should be the declaration in order to be able to save timestamp values with this precision?



Timestamp with a millisecond precision: How to save them in MySQL

Soundcloud&#39;s API gives the duration of it&#39;s tracks as milliseconds. JSON looks like this:

    &quot;duration&quot;: 298999

I&#39;ve tried many functions I found on here to no avail. I&#39;m just looking for something to convert that number to something like looks like this:

    4:59

Here&#39;s one that got close, but doesn&#39;t work. It doesn&#39;t stop the seconds at 60. It goes all the way to 99 which makes no sense. Try entering &quot;187810&quot; as a value of ms, for example.

    var ms = 298999,
    min = Math.floor((ms/1000/60) &lt;&lt; 0),
    sec = Math.floor((ms/1000) % 60);

    console.log(min + &#39;:&#39; + sec);

Thanks for your help!

If you could add in support for hours, too, I would be grateful.

Converting milliseconds to minutes and seconds with Javascript

I have a date inside a string, something like &quot;12-December-2012&quot;.
How can I convert this into milliseconds (long)?

When JAXB marshals a date object (`XMLGregorianCalendar`) into an xsd:dateTime element. How can you specify the format of the resulting XML?

For example:
The default data format uses milliseconds `&lt;StartDate&gt;2012-08-21T13:21:58.000Z&lt;/StartDate&gt;`
I need to omit the milliseconds.  `&lt;StartDate&gt;2012-08-21T13:21:58Z&lt;/StartDate&gt;`

How can I specify the output form/date format that I want it to use?
I&#39;m using `javax.xml.datatype.DatatypeFactory` to create the `XMLGregorianCalendar` object.

    XMLGregorianCalendar xmlCal = datatypeFactory.newXMLGregorianCalendar(cal);

I am wondering if there is a way to get current milliseconds since 1-1-1970 (epoch) using the new `LocalDate`, `LocalTime` or `LocalDateTime` classes of Java 8.

The known way is below:  
  
    long currentMilliseconds = new Date().getTime();
  
  or
  
    long currentMilliseconds = System.currentTimeMillis();

How to get current time in milliseconds in PHP?

i did some research, but still can&#39;t find how to get the days... Here is what I got:

    int seconds = (int) (milliseconds / 1000) % 60 ;
    int minutes = (int) ((milliseconds / (1000*60)) % 60);
    int hours   = (int) ((milliseconds / (1000*60*60)) % 24);
    int days = ????? ;

Please help, I suck at math, thank&#39;s.
