Unix timestamp時間 與 普通時間 轉換方法

下面以java 轉換方法為例 說明
java時間轉換成unix timestamp
import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; /** * @author gdp * @version 建立時間：2016-3-3 上午 10:21:47 */ public class TestUnixTime { public static void main(String[] args) throws ParseException{ //普通時間 轉換 Unix timestamp DateFormat df=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date d = df.format("2016-3-1"); long epoch = d.getTime()/1000; // 獲得 unix timestamp System.out.println("2016-3-1 unix stamp is "+ epoch); // unix timestamp 轉換 普通時間 Date d2 = new Date（epoch * 1000）; } }
| Java | time |
| JavaScript | Math.round(new Date().getTime()/1000) getTime()返回數值的單位是毫秒 |
| 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()) |
| 先 import time 然後 time.time() | |
| Ruby | 獲取Unix時間戳：Time.now 或 Time.new 顯示Unix時間戳：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()) |
| 其他作業系統 (如果Perl被安裝在系統中) |
命令列狀態：perl -e "print time" |
| Java | String date = new java.text.SimpleDateFormat("dd/MM/yyyy HH:mm:ss").format(new java.util.Date(Unix timestamp |
| JavaScript | 先 var unixTimestamp = new Date(Unix timestamp * 1000)然後 commonTime = unixTimestamp.toLocaleString() |
| Linux | date -d @Unix timestamp |
| MySQL | from_unixtime(Unix timestamp) |
| Perl | 先 my $time = Unix timestamp 然後 my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6] |
| PHP | date('r', Unix timestamp) |
| PostgreSQL | SELECT TIMESTAMP WITH TIME ZONE 'epoch' + Unix timestamp) * INTERVAL '1 second'; |
| Python | 先 import time 然後 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") |
| 其他作業系統 (如果Perl被安裝在系統中) |
命令列狀態：perl -e "print scalar(localtime(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) 時間格式: YYYY-MM-DD HH:MM:SS 或 YYMMDD 或 YYYYMMDD |
| Perl | 先 use Time::Local 然後 my $time = timelocal($sec, $min, $hour, $day, $month, $year); |
| PHP | mktime(hour, minute, second, day,month,year) |
| PostgreSQL | SELECT extract(epoch FROM date('YYYY-MM-DD HH:MM:SS')); |
| Python | 先 import time 然後 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) |
