如果你愿意

测量执行时间精确到(hh:mm:ss)的百分之一秒。ff格式) 不需要下载和安装资源包 看起来像一个巨大的DOS书呆子(谁不是呢)

尝试将以下脚本复制到一个新的批处理文件(例如timecmd.bat):

@echo off
@setlocal

set start=%time%

:: Runs your command
cmd /c %*

set end=%time%
set options="tokens=1-4 delims=:.,"
for /f %options% %%a in ("%start%") do set start_h=%%a&set /a start_m=100%%b %% 100&set /a start_s=100%%c %% 100&set /a start_ms=100%%d %% 100
for /f %options% %%a in ("%end%") do set end_h=%%a&set /a end_m=100%%b %% 100&set /a end_s=100%%c %% 100&set /a end_ms=100%%d %% 100

set /a hours=%end_h%-%start_h%
set /a mins=%end_m%-%start_m%
set /a secs=%end_s%-%start_s%
set /a ms=%end_ms%-%start_ms%
if %ms% lss 0 set /a secs = %secs% - 1 & set /a ms = 100%ms%
if %secs% lss 0 set /a mins = %mins% - 1 & set /a secs = 60%secs%
if %mins% lss 0 set /a hours = %hours% - 1 & set /a mins = 60%mins%
if %hours% lss 0 set /a hours = 24%hours%
if 1%ms% lss 100 set ms=0%ms%

:: Mission accomplished
set /a totalsecs = %hours%*3600 + %mins%*60 + %secs%
echo command took %hours%:%mins%:%secs%.%ms% (%totalsecs%.%ms%s total)

使用

如果你把timecmd.bat放在你路径中的一个目录中，你可以在任何地方调用它，像这样:

timecmd [your command]

E.g.

C:\>timecmd pause
Press any key to continue . . .
command took 0:0:1.18

如果你想做输出重定向，你可以这样引用命令:

timecmd "dir c:\windows /s > nul"

这应该可以处理从午夜之前到午夜之后运行的命令，但是如果您的命令运行了24小时或更长时间，则输出将是错误的。

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

不像Unix上的一些功能那样优雅，但是创建一个cmd文件，看起来像这样:

@echo off
time < nul
yourexecutable.exe > c:\temp\output.txt
time < nul
rem on newer windows system you can try time /T

将显示开始和停止时间，如下所示:

The current time is: 10:31:57.92
Enter the new time:
The current time is: 10:32:05.94
Enter the new time:

测量时间的替代方法是简单的“Get-Date”。你不会有转发输出的麻烦。

$start = Get-Date
[System.Threading.Thread]::Sleep(1500)
$(Get-Date) - $start

输出:

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 1
Milliseconds      : 506
Ticks             : 15060003
TotalDays         : 1.74305590277778E-05
TotalHours        : 0.000418333416666667
TotalMinutes      : 0.025100005
TotalSeconds      : 1.5060003
TotalMilliseconds : 1506.0003

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

一个解决方案使用纯PHP为cmd和一个env。变量:

@echo off
setlocal enableextensions

REM set start time env var
FOR /F "tokens=* USEBACKQ" %%F IN (`php -r "echo microtime(true);"`) DO ( SET start_time=%%F )

## PUT_HERE_THE_COMMAND_TO_RUN ##

REM echo elapsed time
php -r "echo 'elapsed: ' . (round(microtime(true) - trim(getenv('start_time')), 2)) . ' seconds' . mb_convert_encoding('
', 'UTF-8', 'HTML-ENTITIES');"

不需要cygwin或不受信任的实用程序。当PHP在本地可用时非常有用 精度和输出格式可以很容易地调整 同样的想法也可以移植到PowerShell
