編程程序獲取當(dāng)前時(shí)間Unix時(shí)間戳（Unix timestamp）方法
| Java | time |
| JavaScript | Math.round(new Date().getTime()/1000) |
| getTime()返回?cái)?shù)值的單位是毫秒 | |
| Unix / Linux | date +%s |
| Microsoft .NET / C# | epoch = (DateTime.Now.ToUniversalTime().Ticks – 621355968000000000) / 10000000 |
| Python | 1） import time? ? 2） time.time() |
| Perl | time |
| PHP | time() |
| MySQL | SELECT unix_timestamp(now()) |
| PostgreSQL | SELECT extract(epoch FROM now()) |
| SQL Server | SELECT DATEDIFF(s, ‘1970-01-01 00:00:00’, GETUTCDATE()) |
| Ruby | 獲取 Unix時(shí)間戳：Time.now? ? or? ?Time.new |
| 顯示 Unix時(shí)間戳：Time.now.to_i | |
| VBScript / ASP | DateDiff(“s”, “01/01/1970 00:00:00”, Now()) |
編程程序賦值時(shí)間變量為Unix時(shí)間戳（Unix timestamp）方法
| Java | String date = 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 |
| Perl | 1）my $time = Unix timestamp? 2）my ($sec, $min, $hour, $day, $month, $year) = (localtime($time))[0,1,2,3,4,5,6] |
| PHP | date(‘r’, Unix timestamp) |
| MySQL | from_unixtime(Unix timestamp) |
| PostgreSQL | SELECT TIMESTAMP WITH TIME ZONE ‘epoch’ + Unix timestamp) * INTERVAL ‘1 second’; |
| Python | 1） import time? ? 2） time.gmtime(Unix timestamp) |
| SQL Server | DATEADD(s, Unix timestamp, ‘1970-01-01 00:00:00’) |
| Ruby | Time.at(Unix timestamp) |
| VBScript / ASP | DateAdd(“s”, Unix timestamp, “01/01/1970 00:00:00”) |
