Unix時(shí)間戳轉(zhuǎn)換工具介紹

Unix時(shí)間戳轉(zhuǎn)換工具,可以將Unix時(shí)間戳轉(zhuǎn)換成標(biāo)準(zhǔn)格式的北京時(shí)間,也可以將標(biāo)準(zhǔn)格式的北京時(shí)間轉(zhuǎn)換為 UNIX 時(shí)間戳;

什么是Unix時(shí)間戳(Unix timestamp):時(shí)間戳是指格林威治時(shí)間1970年01月01日00時(shí)00分00秒(北京時(shí)間1970年01月01日08時(shí)00分00秒)起至現(xiàn)在的總秒數(shù)。

PHP示例Unixtime的用法

獲取當(dāng)前時(shí)間戳:$time = time(); 轉(zhuǎn)換為北京時(shí)間:$datetime = date('Y-m-d H:i:s',$time); 轉(zhuǎn)換為時(shí)間戳:$unixtime = strtotime($datetime);(www.pcjson.com)

1、不同程序語(yǔ)言或數(shù)據(jù)庫(kù)中,獲取現(xiàn)在的Unix時(shí)間戳(Unix timestamp)的方法:

PHP time()
Java time
JavaScript Math.round(new Date().getTime()/1000)
getTime()返回?cái)?shù)值的單位是毫秒
.NET / C# time = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000
MySQL SELECT unix_timestamp(now())
Perl time
PostgreSQL SELECT extract(time FROM now())
Python 先 import time 然后 time.time()
Ruby 獲取Unix時(shí)間戳:Time.now 或 Time.new
顯示Unix時(shí)間戳: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())

2、不同程序語(yǔ)言或數(shù)據(jù)庫(kù)中,實(shí)現(xiàn)普通時(shí)間 → Unix時(shí)間戳(Unix timestamp):

PHP mktime(hour, minute, second, day, month, year)
Java long datetime = 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)
時(shí)間格式: 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);
PostgreSQL SELECT extract(datetime 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', datetime)
Unix / Linux date +%s -d"Jan 1, 1970 00:00:01"
VBScript / ASP DateDiff("s", "01/01/1970 00:00:00", datetime)

3、不同程序語(yǔ)言或數(shù)據(jù)庫(kù)中,Unix時(shí)間戳(Unix timestamp) 轉(zhuǎn)為 普通時(shí)間(年-月-日 時(shí):分:秒):

PHP date('r', Unix timestamp)
Java String datetime = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp * 1000))
JavaScript 先 var unixTimestamp = new Date(Unix timestamp * 1000) 然后 commonTime = unixTimestamp.toLocaleString()
Linux date -d @Unix timestamp
MySQL from_unixtime(Unix timestamp)
Perl 先 my $time = Unix timestamp 然后 my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6]
PostgreSQL SELECT TIMESTAMP WITH TIME ZONE 'time' + Unix timestamp) * INTERVAL '1 second';
Python 先 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")
您的足跡:
