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。

PowerShell为此提供了一个cmdlet，称为Measure-Command。您必须确保在运行PowerShell的机器上是可用的。

PS> Measure-Command { echo hi }

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 0
Ticks             : 1318
TotalDays         : 1.52546296296296E-09
TotalHours        : 3.66111111111111E-08
TotalMinutes      : 2.19666666666667E-06
TotalSeconds      : 0.0001318
TotalMilliseconds : 0.1318

Measure-Command捕获命令的输出。你可以使用Out-Default将输出重定向回控制台:

PS> Measure-Command { echo hi | Out-Default }
hi

Days              : 0
...

正如Makotoe所评论的那样，Measure-Command返回一个TimeSpan对象，因此测量的时间被打印为一堆字段。你可以使用ToString()将对象格式化为时间戳字符串:

PS> (Measure-Command { echo hi | Out-Default }).ToString()
hi
00:00:00.0001318

如果Measure-Command中的命令改变了控制台文本的颜色，使用[console]::ResetColor()将其重置为正常。

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。

@echo off & setlocal

set start=%time%

REM Do stuff to be timed here.
REM Alternatively, uncomment the line below to be able to
REM pass in the command to be timed when running this script.
REM cmd /c %*

set end=%time%

REM Calculate time taken in seconds, to the hundredth of a second.
REM Assumes start time and end time will be on the same day.

set options="tokens=1-4 delims=:."

for /f %options% %%a in ("%start%") do (
    set /a start_s="(100%%a %% 100)*3600 + (100%%b %% 100)*60 + (100%%c %% 100)"
    set /a start_hs=100%%d %% 100
)

for /f %options% %%a in ("%end%") do (
    set /a end_s="(100%%a %% 100)*3600 + (100%%b %% 100)*60 + (100%%c %% 100)"
    set /a end_hs=100%%d %% 100
)

set /a s=%end_s%-%start_s%
set /a hs=%end_hs%-%start_hs%

if %hs% lss 0 (
    set /a s=%s%-1
    set /a hs=100%hs%
)
if 1%hs% lss 100 set hs=0%hs%

echo.

复制并粘贴到一些编辑器，如notepad++，并保存为TimeIt.cmd:

这是对Luke Sampson的nice timecmd.bat的评论/编辑并回复

出于某种原因，这只给我整秒的输出…这对我来说毫无用处。我的意思是，我运行timecmd pause，结果总是1秒，2秒，4秒……甚至是0.00秒!Windows 7。- Camilo Martin 13年9月25日16:00

在某些配置上，分隔符可能不同。以下变化至少应该涵盖大多数西方国家。

set options="tokens=1-4 delims=:,." (added comma)

在添加'，'后，%time%毫秒在我的系统上工作
