javascript中时间戳日期转换[转]
时间戳转换如何在不同编程语言中获取现在的Unix时间戳(Unix timestamp)？
JavatimeJavaScriptMath.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) / 10000000MySQLSELECT unix_timestamp(now())PerltimePHPtime()PostgreSQLSELECT extract(epoch FROM now())Python先 import time 然后 time.time()Ruby获取Unix时间戳：Time.now 或 Time.new
显示Unix时间戳：Time.now.to_iSQL ServerSELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())Unix / Linuxdate +%sVBScript / ASPDateDiff("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？
JavaString date = newjava.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(newjava.util.Date(Unix timestamp * 1000))JavaScript先 var unixTimestamp = new Date(Unix timestamp * 1000) 然后commonTime = unixTimestamp.toLocaleString()Linuxdate -d @Unix timestampMySQLfrom_unixtime(Unix timestamp)Perl先 my $time = Unix timestamp 然后 my ($sec, $min, $hour, $day,$month, $year) = (localtime($time))PHPdate('r', Unix timestamp)PostgreSQLSELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) *INTERVAL '1 second';Python先 import time 然后 time.gmtime(Unix timestamp)RubyTime.at(Unix timestamp)SQL ServerDATEADD(s, Unix timestamp, '1970-01-01 00:00:00')VBScript / ASPDateAdd("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))"
