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。

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%"
)
goto:eof

在程序所在的目录中，键入记事本mytimer.bat，单击“是”创建一个新文件。 粘贴下面的代码，用你的程序替换YourApp.exe，然后保存。 @echo掉 日期/ t 时间/ t YourApp.exe 日期/ t 时间/ t 在命令行中输入mytimer.bat，然后按Enter。

如果您使用的是Windows 2003(注意不支持Windows server 2008及更高版本)，您可以使用Windows server 2003资源工具包，其中包含显示详细执行统计信息的time .exe。这里有一个例子，计时命令“timeit -?”：

C:\>timeit timeit -?
Invalid switch -?
Usage: TIMEIT [-f filename] [-a] [-c] [-i] [-d] [-s] [-t] [-k keyname | -r keyname] [-m mask] [commandline...]
where:        -f specifies the name of the database file where TIMEIT
                 keeps a history of previous timings.  Default is .\timeit.dat
              -k specifies the keyname to use for this timing run
              -r specifies the keyname to remove from the database.  If
                 keyname is followed by a comma and a number then it will
                 remove the slowest (positive number) or fastest (negative)
                 times for that keyname.
              -a specifies that timeit should display average of all timings
                 for the specified key.
              -i specifies to ignore non-zero return codes from program
              -d specifies to show detail for average
              -s specifies to suppress system wide counters
              -t specifies to tabular output
              -c specifies to force a resort of the data base
              -m specifies the processor affinity mask

您可以在Windows 2003资源工具包中获得TimeIt。它不能从微软下载中心直接下载，但仍然可以从archive.org - Windows Server 2003资源工具包工具中获得。

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

powershell的另一种方法:

@echo off
for /f %%t in ('powershell "(get-date).tofiletime()"') do set mst=%%t

rem some commands

powershell ((get-date).tofiletime() - %mst%)

这将以毫秒为单位打印执行时间。
