用潜水艇返回百分之一秒的时间

::tiemeit.cmd
@echo off
Setlocal EnableDelayedExpansion

call :clock 

::call your_command  or more > null to pipe this batch after your_command

call :clock

echo %timed%
pause
goto:eof

:clock
if not defined timed set timed=0
for /F "tokens=1-4 delims=:.," %%a in ("%time%") do ( 
set /A timed = "(((1%%a - 100) * 60 + (1%%b - 100)) * 60 + (1%%c - 100))  * 100 + (1%%d - 100)- %timed%"

我使用的是Windows XP，由于某些原因，time .exe不适合我。我找到了另一种选择——PTIME。这工作得很好。

的例子,

C:\> ptime

ptime 1.0 for Win32, Freeware - http://www.pc-tools.net/
Copyright(C) 2002, Jem Berkes <jberkes@pc-tools.net>

Syntax: ptime command [arguments ...]

ptime will run the specified command and measure the execution time
(run time) in seconds, accurate to 5 millisecond or better. It is an
automatic process timer, or program timer.


C:\> ptime cd

Execution time: 0.015 s

还有TimeMem(2012年3月):

这是一个Windows实用程序，执行一个程序并显示它 执行时间、内存使用和IO统计信息。这与 Unix time实用程序的功能。

The following script uses only "cmd.exe" and outputs the number of milliseconds from the time a pipeline is created to the time that the process preceding the script exits. i.e., Type your command, and pipe the to the script. Example: "timeout 3 | runtime.cmd" should yield something like "2990." If you need both the runtime output and the stdin output, redirect stdin before the pipe - ex: "dir /s 1>temp.txt | runtime.cmd" would dump the output of the "dir" command to "temp.txt" and would print the runtime to the console.

:: --- runtime.cmd ----
@echo off
setlocal enabledelayedexpansion

:: find target for recursive calls
if not "%1"=="" (
    shift /1
    goto :%1
    exit /b
)

:: set pipeline initialization time
set t1=%time%

:: wait for stdin
more > nul

:: set time at which stdin was ready
set t2=!time!

::parse t1
set t1=!t1::= !
set t1=!t1:.= !
set t1=!t1: 0= !

:: parse t2
set t2=!t2::= !
set t2=!t2:.= !
set t2=!t2: 0= !

:: calc difference
pushd %~dp0
for /f %%i in ('%0 calc !t1!') do for /f %%j in ('%0 calc !t2!') do (
    set /a t=%%j-%%i
    echo !t!
)
popd
exit /b
goto :eof

:calc
set /a t=(%1*(3600*1000))+(%2*(60*1000))+(%3*1000)+(%4)
echo !t!
goto :eof

endlocal

我的代码为您提供以毫秒为单位的运行时间，最高可达24小时，它是地区不敏感的，如果代码运行到午夜，则为负值。它使用延迟扩展，应该保存在cmd/bat文件中。

代码之前:

SETLOCAL EnableDelayedExpansion

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t1 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t1=!t1!%t:~15,3%

代码之后:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t2 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t2=!t2!%t:~15,3%
set /a t2-=t1 && if !t2! lss 0 set /a t2+=24*3600000

如果你想让运行时间以HH:mm:ss为单位。000格式，添加:

set /a "h=t2/3600000,t2%%=3600000,m=t2/60000,t2%%=60000" && set t2=00000!t2!&& set t2=!t2:~-5!
if %h% leq 9 (set h=0%h%) && if %m% leq 9 (set m=0%m%)
set t2=%h%:%m%:%t2:~0,2%.%t2:~2,3%

ENDLOCAL

变量t2保存您的运行时间，您可以返回%t2%来显示它。

如果你打开了一个命令窗口并手动调用命令，你可以在每个提示符上显示时间戳，例如:

prompt $d $t $_$P$G

它会给你这样的东西:

23.03.2009 15:45:50 77 C: \ >

如果你有一个小的批处理脚本来执行你的命令，在每个命令之前有一个空行，例如。

(空行) myCommand.exe (下一行空) myCommand2.exe

根据提示符中的时间信息，可以计算出每条命令的执行时间。最好的可能是管道输出到一个文本文件进行进一步分析:

MyBatchFile.bat > output.txt
