下面的脚本模拟*nix纪元时间，但它是本地和区域性的。它应该处理日历边缘情况，包括闰年。如果Cygwin可用，则可以通过指定Cygwin选项来比较epoch值。

我在EST，报告的差异是4小时，这是相对正确的。有一些有趣的解决方案可以删除TZ和区域依赖，但我注意到没有什么微不足道的。

在Perl安装了可用的雇佣解决方案后，运行:

C:\BATCH>time.pl "echo Fine result"
0.01063
Fine result

STDERR出现在被测量的秒之前

#!/usr/bin/perl -w

use Time::HiRes qw();
my $T0 = [ Time::HiRes::gettimeofday ];

my $stdout = `@ARGV`;

my $time_elapsed = Time::HiRes::tv_interval( $T0 );

print $time_elapsed, "\n";
print $stdout;

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。

只要不超过24小时…

@echo off

set starttime=%TIME%
set startcsec=%STARTTIME:~9,2%
set startsecs=%STARTTIME:~6,2%
set startmins=%STARTTIME:~3,2%
set starthour=%STARTTIME:~0,2%
set /a starttime=(%starthour%*60*60*100)+(%startmins%*60*100)+(%startsecs%*100)+(%startcsec%)

:TimeThis
ping localhost 

set endtime=%time%
set endcsec=%endTIME:~9,2%
set endsecs=%endTIME:~6,2%
set endmins=%endTIME:~3,2%
set endhour=%endTIME:~0,2%
if %endhour% LSS %starthour% set /a endhour+=24
set /a endtime=(%endhour%*60*60*100)+(%endmins%*60*100)+(%endsecs%*100)+(%endcsec%)

set /a timetaken= ( %endtime% - %starttime% )
set /a timetakens= %timetaken% / 100
set timetaken=%timetakens%.%timetaken:~-2%

echo.
echo Took: %timetaken% sec.

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。
