计算 Windows 批处理文件中的时间差 [英] Calculate time difference in Windows batch file

问题描述

如何获取批处理文件中两次之间的差异?因为我想打印成 HTML 文件.

How can I get the difference between two times in a Batch file? Because I want to print it in an HTML file.

我认为这是可能的，但事实并非如此.

I thought this would be possible, but it isn't.

Set "tijd=%time%"
echo %tijd%
echo %time%-%tijd%

结果:

11:07:48,85
11:16:58,99-11:07:48,85

但我想要的是:

00:09:10,14

或 9 分 10 秒或 550 秒

Or 9 minutes and 10 seconds or 550 seconds

推荐答案

如这里回答:如何才能我使用 Windows 批处理文件来衡量控制台应用程序的性能?

下面的批处理程序"应该做你想做的.请注意，它以厘秒而不是毫秒为单位输出数据.使用命令的精度只有厘秒.

Below batch "program" should do what you want. Please note that it outputs the data in centiseconds instead of milliseconds. The precision of the used commands is only centiseconds.

这是一个示例输出:

STARTTIME: 13:42:52,25
ENDTIME: 13:42:56,51
STARTTIME: 4937225 centiseconds
ENDTIME: 4937651 centiseconds
DURATION: 426 in centiseconds
00:00:04,26

这是批处理脚本:

@echo off
setlocal

rem The format of %TIME% is HH:MM:SS,CS for example 23:59:59,99
set STARTTIME=%TIME%

rem here begins the command you want to measure
dir /s > nul
rem here ends the command you want to measure

set ENDTIME=%TIME%

rem output as time
echo STARTTIME: %STARTTIME%
echo ENDTIME: %ENDTIME%

rem convert STARTTIME and ENDTIME to centiseconds
set /A STARTTIME=(1%STARTTIME:~0,2%-100)*360000 + (1%STARTTIME:~3,2%-100)*6000 + (1%STARTTIME:~6,2%-100)*100 + (1%STARTTIME:~9,2%-100)
set /A ENDTIME=(1%ENDTIME:~0,2%-100)*360000 + (1%ENDTIME:~3,2%-100)*6000 + (1%ENDTIME:~6,2%-100)*100 + (1%ENDTIME:~9,2%-100)

rem calculating the duratyion is easy
set /A DURATION=%ENDTIME%-%STARTTIME%

rem we might have measured the time inbetween days
if %ENDTIME% LSS %STARTTIME% set set /A DURATION=%STARTTIME%-%ENDTIME%

rem now break the centiseconds down to hors, minutes, seconds and the remaining centiseconds
set /A DURATIONH=%DURATION% / 360000
set /A DURATIONM=(%DURATION% - %DURATIONH%*360000) / 6000
set /A DURATIONS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000) / 100
set /A DURATIONHS=(%DURATION% - %DURATIONH%*360000 - %DURATIONM%*6000 - %DURATIONS%*100)

rem some formatting
if %DURATIONH% LSS 10 set DURATIONH=0%DURATIONH%
if %DURATIONM% LSS 10 set DURATIONM=0%DURATIONM%
if %DURATIONS% LSS 10 set DURATIONS=0%DURATIONS%
if %DURATIONHS% LSS 10 set DURATIONHS=0%DURATIONHS%

rem outputing
echo STARTTIME: %STARTTIME% centiseconds
echo ENDTIME: %ENDTIME% centiseconds
echo DURATION: %DURATION% in centiseconds
echo %DURATIONH%:%DURATIONM%:%DURATIONS%,%DURATIONHS%

endlocal
goto :EOF
