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 SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second';
Python import time 然后 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)?
   
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 use Time::Local 然后 my $time = timelocal($sec, $min, $hour, $day, $month, $year);
PHP mktime(hour, minute, second, day, month, year)
PostgreSQL SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS'));
Python 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)
