Unix时间戳转北京时间

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(newDate().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：time

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？

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

JavaScript：先 var unixTimestamp = newDate(Unix timestamp * 1000) 然后 commonTime = unixTimestamp.toLocaleString()

Linux：date -d @Unix timestamp

MySQL：from_unixtime(Unix timestamp)

Perl：先 my $time = Unix timestamp然后 my ($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 然后time.gmtime(Unix timestamp)

Ruby：Time.at(Unix timestamp)

SQL Server：DATEADD(s, Unix timestamp, '1970-01-0100:00:00')

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

其他操作系统(如果Perl被安装在系统中)：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)？

Java：long epoch = newjava.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)时间格式:YYYY-MM-DD HH:MM:SS 或 YYMMDD 或 YYYYMMDD

Perl：先 use Time::Local 然后 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-DDHH:MM:SS'));

Python：先 import time 然后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"

VBScript / ASP：DateDiff("s", "01/01/1970 00:00:00",time)
