time

Math.round(new Date().getTime()/1000)
getTime()返回数值的单位是毫秒

epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000

SELECT unix_timestamp(now())

time

time()

SELECT extract(epoch FROM now())

先 import time 然后 time.time()

获取Unix时间戳：Time.now 或 Time.new
显示Unix时间戳Time.now.to_i

SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())

date +%s

DateDiff("s", "01/01/1970 00:00:00", Now())

(如果Perl被安装在系统中)
命令行状态：perl -e "print time"

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

先 var unixTimestamp = new Date(Unix timestamp * 1000) 然后    commonTime = unixTimestamp.toLocaleString()

date -d @Unix timestamp

from_unixtime(Unix timestamp)

先 my $time = Unix timestamp 然后  my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]

date('r', Unix timestamp)

SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second';

先 import time 然后 time.gmtime(Unix timestamp)

Time.at(Unix timestamp)

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

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

(如果Perl被安装在系统中)
命令行状态：perl -e "print scalar(localtime(Unix timestamp))"

long epoch = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").parse("01/01/1970 01:00:00");

var commonTime = new Date(Date.UTC(year, month - 1, day, hour, minute, second))

SELECT unix_timestamp(time)
时间格式: YYYY-MM-DD HH:MM:SS 或 YYMMDD 或 YYYYMMDD

先 use Time::Local 然后    my $time = timelocal($sec, $min, $hour, $day, $month, $year);

mktime(hour, minute, second, month, day, year)

SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS'));

先 import time 然后 int(time.mktime(time.strptime('YYYY-MM-DD HH:MM:SS', '%Y-%m-%d %H:%M:%S')))

Time.local(year, month, day, hour, minute, second)

SELECT DATEDIFF(s, '1970-01-01 00:00:00', time)

date +%s -d"Jan 1, 1970 00:00:01"

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