计算Windowsbatch file中的时差

概述计算Windowsbatch file中的时差

如何在batch file中获得两次之间的差异？ 因为我想打印在HTML文件中。

我认为这是可能的，但事实并非如此。

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

结果：

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

但是我想要的是：

如何在不使用ls -ln的情况下在C中打印文件详细信息

如何杀死特定的进程使用％cpu在给定的时间在Python的Python？

C中的当前微秒时间？

windows批处理脚本：在日志中显示date，时间和所有输出

在连接LAN电缆的两台windows 7计算机之间同步时间

00:09:10,14

或9分10秒或550秒

什么是CLOCK_TAI的时代？

需要关于timespec结构的清晰的想法

如何停止在linux上倒退的时间？

linux的时间命令微秒或更好的精度

实时了解localtime（）和localtime_r（）的时区变化

@echo off rem Get start time: for /F "tokens=1-4 delims=:.," %%a in ("%time%") do ( set /A "start=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100" ) rem Any process here... rem Get end time: for /F "tokens=1-4 delims=:.," %%a in ("%time%") do ( set /A "end=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100" ) rem Get elapsed time: set /A elapsed=end-start rem Show elapsed time: set /A hh=elapsed/(60*60*100),rest=elapsed%%(60*60*100),mm=rest/(60*100),rest%%=60*100,ss=rest/100,cc=rest%%100 if %mm% lss 10 set mm=0%mm% if %ss% lss 10 set ss=0%ss% if %cc% lss 10 set cc=0%cc% echo %hh%:%mm%:%ss%,%cc%

编辑2017-05-09： 添加更短的方法

我开发了一个较短的方法来获得相同的结果，所以我忍不住要在这里发表。 两个for分隔时间部分的命令和三个用于在结果中插入前导零的if命令由两个长的算术表达式替代，甚至可以组合成一个较长的行。

该方法包括直接将“HH：MM：SS.CC”格式的变量转换为将时间转换为厘秒的公式，相应地转换为下面给出的映射方案：

HH : MM : SS . CC (((10 HH %%100)*60+1 MM %%100)*60+1 SS %%100)*100+1 CC %%100

也就是说，插入(((10开头，用%%100)*60+1代替冒号%%100)*60+1 ，用%%100)*100+1代替点，最后插入%%100 ;最后，计算结果字符串作为一个算术表达式，在时间变量中有两个不同的子字符串需要被替换，所以转换必须在两行中完成，为了获得一个经过的时间，使用(endTime)-(startTime)表达式并替换两个时间字符串在同一行。

编辑2017/06/14： 增加了语言环境独立调整

@echo off setlocal EnableDelayedExpansion set "startTime=%time: =0%" set /P "=Any process here..." set "endTime=%time: =0%" rem Get elapsed time: set "end=!endTime:%time:~8,1%=%%100)*100+1!" & set "start=!startTime:%time:~8,1%=%%100)*100+1!" set /A "elap=((((10!end:%time:~2,1%=%%100)*60+1!%%100)-((((10!start:%time:~2,1%=%%100)*60+1!%%100)" rem Convert elapsed time to HH:MM:SS:CC format: set /A "cc=elap%%100+100,elap/=100,ss=elap%%60+100,elap/=60,mm=elap%%60+100,hh=elap/60+100" echo Start: %startTime% echo End: %endTime% echo Elapsed: %hh:~1%%time:~2,1%%mm:~1%%time:~2,1%%ss:~1%%time:~8,1%%cc:~1%

你可以在这个答案中查看这个方法的详细解释。

在这里回答： 如何使用windows批处理文件来衡量控制台应用程序的性能？

下面的批次“程序”应该做你想做的。 请注意，它以毫秒为单位输出数据，而不是毫秒。 使用的命令的精确度仅为厘秒。

这是一个输出示例：

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

Aacini代码的重新散列，因为您很可能将开始时间设置为一个变量，并希望保存该数据以进行输出：

@echo off rem ****************** MAIN CODE SECTION set STARTTIME=%TIME% rem Your code goes here (remove the Ping line) Ping -n 4 -w 1 127.0.0.1 >Nul set ENDTIME=%TIME% rem ****************** END MAIN CODE SECTION rem Change formatting for the start and end times for /F "tokens=1-4 delims=:.," %%a in ("%sTARTTIME%") do ( set /A "start=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100" ) for /F "tokens=1-4 delims=:.," %%a in ("%ENDTIME%") do ( set /A "end=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100" ) rem Calculate the elapsed time by subtracting values set /A elapsed=end-start rem Format the results for output set /A hh=elapsed/(60*60*100),cc=rest%%100 if %hh% lss 10 set hh=0%hh% if %mm% lss 10 set mm=0%mm% if %ss% lss 10 set ss=0%ss% if %cc% lss 10 set cc=0%cc% set DURATION=%hh%:%mm%:%ss%,%cc% echo Start : %sTARTTIME% echo Finish : %ENDTIME% echo --------------- echo Duration : %DURATION%

输出：

Start : 11:02:45.92 Finish : 11:02:48.98 --------------- Duration : 00:00:03,06

根据以前的答案，这里是可重复使用的“程序”和计算经过时间的使用示例：

@echo off setlocal set starttime=%TIME% echo Start Time: %starttime% REM --------------------------------------------- REM --- PUT THE CODE YOU WANT TO MEASURE HERE --- REM --------------------------------------------- set endtime=%TIME% echo End Time: %endtime% call :elapsed_time %starttime% %endtime% duration echo Duration: %duration% endlocal echo on & goto :eof REM --- HELPER PROCEDURES --- :time_to_centiseconds :: %~1 - time :: %~2 - centiseconds output variable setlocal set _time=%~1 for /F "tokens=1-4 delims=:.," %%a in ("%_time%") do ( set /A "_result=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100" ) endlocal & set %~2=%_result% goto :eof :centiseconds_to_time :: %~1 - centiseconds :: %~2 - time output variable setlocal set _centiseconds=%~1 rem Now break the centiseconds down to hors,seconds and the remaining centiseconds set /A _h=%_centiseconds% / 360000 set /A _m=(%_centiseconds% - %_h%*360000) / 6000 set /A _s=(%_centiseconds% - %_h%*360000 - %_m%*6000) / 100 set /A _hs=(%_centiseconds% - %_h%*360000 - %_m%*6000 - %_s%*100) rem some formatting if %_h% LSS 10 set _h=0%_h% if %_m% LSS 10 set _m=0%_m% if %_s% LSS 10 set _s=0%_s% if %_hs% LSS 10 set _hs=0%_hs% set _result=%_h%:%_m%:%_s%.%_hs% endlocal & set %~2=%_result% goto :eof :elapsed_time :: %~1 - time1 - start time :: %~2 - time2 - end time :: %~3 - elapsed time output setlocal set _time1=%~1 set _time2=%~2 call :time_to_centiseconds %_time1% _centi1 call :time_to_centiseconds %_time2% _centi2 set /A _duration=%_centi2%-%_centi1% call :centiseconds_to_time %_duration% _result endlocal & set %~3=%_result% goto :eof

使用一个单一的功能，可以自定义计量单位或格式化。 每次该函数被调用时没有参数，我们重新开始初始时间。

@ECHO OFF ECHO. ECHO DEMO timer function ECHO -------------------- SET DELAY=4 :: First we call the function without any parameters to set the starting time CALL:timer :: We put some code we want to measure ECHO. ECHO Making some delay,please wait... ECHO.

修正了Gynnad领先的0问题。 我用两条线固定它

SET STARTTIME=%sTARTTIME: =0% SET ENDTIME=%ENDTIME: =0%

完整脚本（ CalculateTime.cmd ）：

@ECHO OFF :: FUNCTIONS :__START_TIME_MEASURE SET STARTTIME=%TIME% SET STARTTIME=%sTARTTIME: =0% EXIT /B 0 :__Stop_TIME_MEASURE SET ENDTIME=%TIME% SET ENDTIME=%ENDTIME: =0% SET /A STARTTIME=(1%sTARTTIME:~0,2%-100) SET /A ENDTIME=(1%ENDTIME:~0,2%-100) SET /A DURATION=%ENDTIME%-%sTARTTIME% IF %DURATION% == 0 SET TIMEDIFF=00:00:00,00 && EXIT /B 0 IF %ENDTIME% LSS %sTARTTIME% SET /A DURATION=%sTARTTIME%-%ENDTIME% 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) 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% SET TIMEDIFF=%DURATIONH%:%DURATIONM%:%DURATIONS%,%DURATIONHS% EXIT /B 0 :: USAGE :: Start Measuring CALL :__START_TIME_MEASURE :: Print Message on Screen without lineFeed ECHO|SET /P=Execute Job... :: Some Time pending Jobs here :: '> Nul 2>&1' Dont show any Messages or Errors on Screen MyJob.exe > Nul 2>&1 :: Stop Measuring CALL :__Stop_TIME_MEASURE :: Finish the Message 'Execute Job...' and print measured Time ECHO [Done] (%TIMEDIFF%) :: Possible Result :: Execute Job... [Done] (00:02:12,31) :: Between 'Execute Job... ' and '[Done] (00:02:12,31)' the Job will be executed

Aacini最新的代码展示了一个非常棒的变量替换方法。

这是一个耻辱，这不是区域格式证明 – 它失败了这么多层次。

这里有一个简短的修复，保持替换+数学方法不变：

@echo off setlocal EnableDelayedExpansion set "startTime=%time: =0%" & rem AveYo: fix single digit hour set /P "=Any process here..." set "endTime=%time: =0%" & rem AveYo: fix single digit hour rem Aveyo: Regional format fix with just one aditional line for /f "tokens=1-3 delims=0123456789" %%i in ("%endTime%") do set "ColON=%%i" & set "DOT=%%k" rem Get elapsed time: set "end=!endTime:%DOT%=%%100)*100+1!" & set "start=!startTime:%DOT%=%%100)*100+1!" set /A "elap=((((10!end:%ColON%=%%100)*60+1!%%100)-((((10!start:%ColON%=%%100)*60+1!%%100)" rem Aveyo: Fix 24 hours set /A "elap=!elap:-=8640000-!" rem Convert elapsed time to HH:MM:SS:CC format: set /A "cc=elap%%100+100,hh=elap/60+100" echo Start: %startTime% echo End: %endTime% echo Elapsed: %hh:~1%%ColON%%mm:~1%%ColON%%ss:~1%%DOT%%cc:~1% & rem AveYo: display as regional pause

“精益和平均”的定时器与区域格式，24小时和混合输入的支持

适应Aacini的替代方法主体，没有IF，只有一个FOR（我的区域修复）

1：将文件timer.bat放置在％PATH％或当前目录的某处

@echo off & rem :AveYo: compact timer function with Regional format,24-hours and mixed input support if not defined timer_set (if not "%~1"=="" (call set "timer_set=%~1") else set "timer_set=%TIME: =0%") & goto :eof (if not "%~1"=="" (call set "timer_end=%~1") else set "timer_end=%TIME: =0%") & setlocal EnableDelayedExpansion for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n) set "TE=!timer_end:%DE%=%%100)*100+1!" & set "TS=!timer_set:%DS%=%%100)*100+1!" set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!" set/A "cc=T%%100+100,T/=100,ss=T%%60+100,T/=60,mm=T%%60+100,hh=T/60+100" set "value=!hh:~1!%CE%!mm:~1!%CE%!ss:~1!%DE%!cc:~1!" & if "%~2"=="" echo/!value! endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof

用法：

定时器 ＆回声start_cmds＆超时/吨3＆回声end_cmds＆ 定时器

定时器和计时器 “23：23：23,00”

定时器 “23：23：23,00”和计时器

定时器 “13.23.23,00”和计时器 “03：03：03.00”

定时器和计时器 “0：00：00.00”no＆cmd / v：on / c直到午夜=！timer_end！

输入现在可以混合，对于那些不太可能的，但是在执行期间可能的时间格式改变

2：功能：与批处理脚本捆绑在一起的定时器 （下面的示例用法）：

@echo off set "TIMER=call :timer" & rem short macro echo. echo EXAMPLE: call :timer timeout /t 3 >nul & rem Any process here.. call :timer echo. echo SHORT MACRO: %TIMER% & timeout /t 1 & %TIMER% echo. echo TEST input: set "start=22:04:04.58" set "end=04.22.44,22" echo %start% ~ start & echo %end% ~ end call :timer "%start%" call :timer "%end%" echo. %TIMER% & %TIMER% "00:00:00.00" no echo UNTIL MIDNIGHT: %timer_end% echo. pause exit /b

::测试它，复制粘贴上面和下面的代码部分

rem :AveYo: compact timer function with Regional format,24-hours and mixed input support :timer Usage " call :timer [input - optional] [no - optional]" :i Result printed on second call,saved to timer_end if not defined timer_set (if not "%~1"=="" (call set "timer_set=%~1") else set "timer_set=%TIME: =0%") & goto :eof (if not "%~1"=="" (call set "timer_end=%~1") else set "timer_end=%TIME: =0%") & setlocal EnableDelayedExpansion for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n) set "TE=!timer_end:%DE%=%%100)*100+1!" & set "TS=!timer_set:%DS%=%%100)*100+1!" set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!" set/A "cc=T%%100+100,hh=T/60+100" set "value=!hh:~1!%CE%!mm:~1!%CE%!ss:~1!%DE%!cc:~1!" & if "%~2"=="" echo/!value! endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof

回声是打印变量值的命令，可能不能处理任何数学。
