如何在不同编程语言中实现普通时间转为Unix时间戳-前端收藏

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	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-DD HH: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)
