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。

driblio的答案可以短一点(虽然可读性不高)

@echo off

:: Calculate the start timestamp
set _time=%time%
set /a _hours=100%_time:~0,2%%%100,_min=100%_time:~3,2%%%100,_sec=100%_time:~6,2%%%100,_cs=%_time:~9,2%
set /a _started=_hours*60*60*100+_min*60*100+_sec*100+_cs


:: yourCommandHere


:: Calculate the difference in cSeconds
set _time=%time%
set /a _hours=100%_time:~0,2%%%100,_min=100%_time:~3,2%%%100,_sec=100%_time:~6,2%%%100,_cs=%_time:~9,2%
set /a _duration=_hours*60*60*100+_min*60*100+_sec*100+_cs-_started

:: Populate variables for rendering (100+ needed for padding)
set /a _hours=_duration/60/60/100,_min=100+_duration/60/100%%60,_sec=100+(_duration/100%%60%%60),_cs=100+_duration%%100

echo Done at: %_time% took : %_hours%:%_min:~-2%:%_sec:~-2%.%_cs:~-2%

::prints something like:
::Done at: 12:37:53,70 took: 0:02:03.55

根据Luke Sampson的评论，这个版本是八进制安全的，尽管任务应该在24小时内完成。

根据您使用的Windows版本不同，只需运行bash就会进入bash模式。这将允许您使用PowerShell上不能直接使用的一系列命令(如time命令)。计时你的命令现在像执行一样简单:

# The clause <your-command> (without the angle brackets) denotes the command you want to run.
$ time <your-command>

注意:在Bash模式下运行exit可以轻松退出Bash模式并返回到主流shell。

在尝试了其他方法(如Measure-Command)后，这对我来说非常有效(Windows 10)，这些方法有时会产生不需要的统计数据。希望这对你也有用。

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。

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.

Execution time: 0.015 s

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.
