如何在不同编程语言中获取现在的Unix时间戳(Unix timestamp)？

Java	time
JavaScript	Math.round(new Date().getTime()/1000) getTime()返回数值的单位是毫秒
Microsoft .NET / C#	epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000
MySQL	SELECT unix_timestamp(now())
Perl
PHP	time()
PostgreSQL	SELECT extract(epoch FROM now())
Python	先 import time 然后 time.time()
Ruby	获取Unix时间戳：Time.now 或 Time.new 显示Unix时间戳：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())
其他操作系统 (如果Perl被安装在系统中)	命令行状态：perl -e "print time"

如何在不同编程语言中实现Unix时间戳(Unix timestamp) → 普通时间？

	String date = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp * 1000))
	先 var unixTimestamp = new Date(Unix timestamp * 1000) 然后commonTime = unixTimestamp.toLocaleString()
Linux	date -d @Unix timestamp
	from_unixtime(Unix timestamp)
	先 my $time = Unix timestamp 然后 my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]
	date('r', Unix timestamp)
	SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second';
	先 import time 然后 time.gmtime(Unix timestamp)
	Time.at(Unix timestamp)
	DATEADD(s, Unix timestamp, '1970-01-01 00:00:00')
	DateAdd("s", Unix timestamp, "01/01/1970 00:00:00")
	命令行状态：perl -e "print scalar(localtime(Unix timestamp))"

如何在不同编程语言中实现普通时间 → Unix时间戳(Unix timestamp)？

	long epoch = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse("01/01/1970 01:00:00");
	var commonTime = new Date(Date.UTC(year, month - 1, day, hour,minute, second))
	SELECT unix_timestamp(time) 时间格式: YYYY-MM-DD HH:MM:SS 或 YYMMDD 或 YYYYMMDD
	先 use Time::Local 然后 my $time = timelocal($sec, $min, $hour, $day, $month, $year);
	mktime(hour, minute, second, month, day, year)
	SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS'));
	先 import time 然后 int(time.mktime(time.strptime('YYYY-MM-DD HH:MM:SS', '%Y-%m-%d %H:%M:%S')))
	Time.local(year, month, day, hour, minute, second)
	SELECT DATEDIFF(s, '1970-01-01 00:00:00', time)
	date +%s -d"Jan 1, 1970 00:00:01"
	DateDiff("s", "01/01/1970 00:00:00", time)
