How can I generate Unix timestamps?

Question

Related question is "Datetime To Unix timestamp", but this question is more general.

I need Unix timestamps to solve my last question. My interests are Python, Ruby and Haskell, but other approaches are welcome.

What is the easiest way to generate Unix timestamps?

Answer 1

curl icanhazepoch.com

Basically it's unix timestamps as a service (UTaaS)

Answer 2

In python add the following lines to get a time stamp:

>>> import time
>>> time.time()
1335906993.995389
>>> int(time.time())
1335906993

Answer 3

public static Int32 GetTimeStamp()
    {
        try
        {
            Int32 unixTimeStamp;
            DateTime currentTime = DateTime.Now;
            DateTime zuluTime = currentTime.ToUniversalTime();
            DateTime unixEpoch = new DateTime(1970, 1, 1);
            unixTimeStamp = (Int32)(zuluTime.Subtract(unixEpoch)).TotalSeconds;
            return unixTimeStamp;
        }
        catch (Exception ex)
        {
            Debug.WriteLine(ex);
            return 0;
        }
    }

Answer 4

For completeness, PHP:

php -r 'echo time();'

In BASH:

clitime=$(php -r 'echo time();')
echo $clitime

Answer 5

In Haskell...

To get it back as a POSIXTime type:

import Data.Time.Clock.POSIX
getPOSIXTime

As an integer:

import Data.Time.Clock.POSIX
round `fmap` getPOSIXTime

Answer 6

in Ruby:

>> Time.now.to_i
=> 1248933648
