透過Bat計算編譯的時間

以下的程式碼，可以協助使用者編譯程式，像是原本要打nmake uefi64
只要直接打
% vb
就可以啦，vb是variable build的簡稱啦~
若要執行nmake clean，可以打
% vb clean

這裡要注意的是，在bat中，%是轉換為其它進位，真正餘數運算元是%%

以下是程式碼
vb.bat

@ECHO OFF

REM ========== GET THE START TIME (DO NOT MODIFY) ==========
SET StartTime=%time%
FOR /F "delims=:. tokens=1-3" %%p IN ("%StartTime%") DO (
  SET /A StartTotalTime=%%p*60*60+%%q*60+%%r
)

REM ========== SET THE DEFAULT VALUE (DO NOT MODIFY) ==========
IF "%1" EQU "" (
  SET TARGET=uefi64
) ELSE (
  SET TARGET=%1
)

REM ========== EXECUTE NMAKE (DO NOT MODIFY) ==========
ECHO NMAKE %TARGET%
CALL NMAKE %TARGET%
@ECHO OFF
GOTO END

:END

REM ========== GET THE END TIME (DO NOT MODIFY) ==========
SET EndTime=%time%
FOR /F "delims=:. tokens=1-3" %%p IN ("%EndTime%") DO (
  SET /A EndTotalTime=%%p*60*60+%%q*60+%%r
)

REM ========== Summary (DO NOT MODIFY) ==========
SET /A TotalTime=%EndTotalTime%-%StartTotalTime%
SET /A Hour=%TotalTime%/3600
SET /A Second=(%TotalTime%)%%60
SET /A Minute=(%TotalTime%-%Hour%*3600-%Second%)/60
ECHO Total: %Hour%:%Minute%:%Second% (From %StartTime% to %EndTime%)

REM ========== Jump the Hint Window  (DO NOT MODIFY) ==========
cscript D:\Devtls\Bat\CompilerDoneMsg.vbs %TARGET% //Nologo

CompilerDoneMsg.vbs

If WScript.Arguments.Count() = 0 Then
  MsgBox " CompilerDone ", vbSystemModal
Else
  '
  'Display first Argument only.
  '
  MsgBox " CompilerDone ", vbSystemModal, WScript.Arguments(0)
End If
