时间戳 介绍 | Introduce timestamp


在不同编程语言中Unix时间戳的函数(Unix timestamp)

语言 函数
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普通时间 → Unix时间戳(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)
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, month, day, 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)
