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。

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

Version Number:   Windows NT 5.2 (Build 3790)

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。

如果你安装了CMake，你可以运行下面的命令。

cmake -E time <the_command_to_measure_run_time>

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

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。

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。
