在Haskell

import Data.Time.Clock.POSIX

main :: IO ()
main = print . floor =<< getPOSIXTime

在去

import "time"
t := time.Unix()

in C

time(); // in time.h POSIX

// for Windows time.h
#define UNIXTIME(result)   time_t localtime; time(&localtime); struct tm* utctime = gmtime(&localtime); result = mktime(utctime);

在斯威夫特

NSDate().timeIntervalSince1970 // or Date().timeIntervalSince1970

在Haskell…

要将它作为POSIXTime类型返回:

import Data.Time.Clock.POSIX
getPOSIXTime

整数形式:

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

在python中添加以下代码行来获取时间戳:

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

在Perl中:

>> time
=> 1335552733

为了完整起见，PHP:

php -r 'echo time();'

在BASH中:

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

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;
        }
    }
