    How do you get a timestamp in programming language?


    Get time timestamp in Java:
    first import the file
    import java.sql.Timestamp;
              import java.util.Date;

    and, then just defined following code

             java.util.Date date= new java.util.Date();
          System.out.println(new Timestamp(date.getTime()));

    Get timestamp in Java script:

    the following returns the number of milliseconds since the epoch.

         new Date().getTime();

    Or on browsers that support ES5 (notably not IE8 and earlier), you can use Date.now:

          Date.now();

    which is really easily shimmed for older browsers:

          if (!Date.now) {
            Date.now = function() { return new Date().getTime(); };
        }

    Get timestamp in IOS:


    NSString * timestamp = [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];

    (times 1000 for milliseconds, otherwise, take that out)

    If You're using it all the time, it might be nice to declare a macro

    #define TimeStamp [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000]

    Then Call it like this:

    NSString * timestamp = TimeStamp;

    Or as a method:

    - (NSString *) timeStamp {
        return [NSString stringWithFormat:@"%f",[[NSDate date] timeIntervalSince1970] * 1000];
    }



    Get timestamp in PHP:

    here is the function get timestamp in php:

    <?php
    $t=time();
    echo($t . "<br>");
    echo(date("Y-m-d",$t));
    ?>


    Get timestamp in C#:

    Function that creates a timestamp in c#

    public static String GetTimestamp(this DateTime value)
    {
        return value.ToString("yyyyMMddHHmmssffff");
    }

    Get timestamp in Python:

    here is the simple way to get time in python;

    Python 2.7.3 (default, Apr 24 2012, 00:00:54) 
    [GCC 4.7.0 20120414 (prerelease)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import time
    >>> ts = time.time()
    >>> print ts
    1355563265.81
    >>> import datetime
    >>> st = datetime.datetime.fromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S')
    >>> print st
    2012-12-15 01:21:05
    >>>

    Get timestamp in Perl:

    getting time in perl for this way:


    If you want to control the format of the timestamp, I usually throw in a subroutine like the following. This will return a scalar in the format of "20120928 08:35:12".

    sub getCurrentTime {

        my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst)=localtime(time);
        my $nice_timestamp = sprintf ( "%04d%02d%02d %02d:%02d:%02d",
                                       $year+1900,$mon+1,$mday,$hour,$min,$sec);
        return $nice_timestamp;
    }

    Then change your code to:

    my $timestamp = getCurrentTime ();



    Happy Coding!!!
