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!!!
