各种方法获取当前时间戳(Unix Timestamp)

Perl time PHP time() Ruby Time.now (or Time.new). To display the epoch: Time.now.to_i Python import time first, then int(time.time()) Java long epoch = System.currentTimeMillis()/1000; Microsoft .NET C# epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000; VBScript/ASP DateDiff("s", "01/01/1970 00:00:00", Now()) Erlang calendar:datetime_to_gregorian_seconds(calendar:now_to_universal_time( now()))-719528*24*3600. ORelement(1, now()) * 10000 + element(2, now()). MySQL SELECT unix_timestamp(now()) PostgreSQL SELECT extract(epoch FROM now()); Oracle PL/SQL SELECT (SYSDATE - TO_DATE('01-01-1970 00:00:00', 'DD-MM-YYYY HH24:MI:SS')) * 24 * 60 * 60 FROM DUAL SQL Server SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE()) JavaScript Math.round(new Date().getTime()/1000.0) getTime() returns time in milliseconds. Unix/Linux Shell date +%s PowerShell Get-Date -UFormat "%s" Produces: 1279152364.63599 Actionscript (new Date()).time Other OS’s Command line: perl -e "print time" (If Perl is installed on your system) ColdFusion (CFML) MX 6.1+ #int( getTickCount() / 1000 )# Bash Command Line: date +%s 相关资源：python入门教程(PDF版)
