time

JavaScript

Math.round(new Date().getTime()/1000)

getTime()返回數值的單位是毫秒

Microsoft .NET / C#

epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000

MySQL

SELECT unix_timestamp(now())

Perl

time

PHP

time()

PostgreSQL

SELECT extract(epoch FROM now())

Python

先 import time 然後 time.time()

Ruby

獲取Unix時間戳：Time.now 或 Time.new

顯示Unix時間戳：Time.now.to_i

SQL Server

SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())

Unix / Linux

date +%s

VBScript / ASP

DateDiff("s", "01/01/1970 00:00:00", Now())

其他作業系統

(如果Perl被安裝在系統中)

命令列狀態：perl -e "print time"

Java

String date = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp * 1000))

JavaScript

先 var unixTimestamp = new Date(Unix timestamp * 1000) 然後 commonTime = unixTimestamp.toLocaleString()

Linux

date -d @Unix timestamp

MySQL

from_unixtime(Unix timestamp)

Perl

先 my $time = Unix timestamp 然後 my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]

PHP

date('r', Unix timestamp)

PostgreSQL

SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second';

Python

先 import time 然後 time.gmtime(Unix timestamp)

Ruby

Time.at(Unix timestamp)

SQL Server

DATEADD(s, Unix timestamp, '1970-01-01 00:00:00')

VBScript / ASP

DateAdd("s", Unix timestamp, "01/01/1970 00:00:00")

其他作業系統

(如果Perl被安裝在系統中)

命令列狀態：perl -e "print scalar(localtime(Unix timestamp))"

Java

long epoch = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse("01/01/1970 01:00:00");

JavaScript

var commonTime = new Date(Date.UTC(year, month - 1, day, hour, minute, second))

MySQL

SELECT unix_timestamp(time)

時間格式: YYYY-MM-DD HH:MM:SS 或 YYMMDD 或 YYYYMMDD

Perl

先 use Time::Local 然後 my $time = timelocal($sec, $min, $hour, $day, $month, $year);

PHP

mktime(hour, minute, second, month, day, year)

PostgreSQL

SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS'));

Python

先 import time 然後 int(time.mktime(time.strptime('YYYY-MM-DD HH:MM:SS', '%Y-%m-%d %H:%M:%S')))

Ruby

Time.local(year, month, day, hour, minute, second)

SQL Server

SELECT DATEDIFF(s, '1970-01-01 00:00:00', time)

Unix / Linux

date +%s -d"Jan 1, 1970 00:00:01"
