java unix时间戳转换

把java时间戳转换成unix时间戳:

Timestamp appointTime=Timestamp.valueOf(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()))
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
				Date date = df.parse(String.valueOf(appointTime));
				long s=date.getTime();
String unixDate=String.valueOf(s).substring(0, 10);	

把unix时间戳转换成java时间戳:

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

?

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 time
PHP time()
PostgreSQL SELECT extract(epoch FROM now())
Python import time 然后 time.time()
Ruby 获取Unix时间戳:Time.now 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?
? ?
JavaScript var unixTimestamp = new Date(Unix timestamp * 1000) 然后 commonTime = unixTimestamp.toLocaleString()
Linux date -d @Unix timestamp
MySQL from_unixtime(Unix timestamp)
Perl 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
