DATEDIFF with specific conditions

I just got some time so I re wrote the formula with break time and based on minute calcualtion. please check the attached file:

Production Time = 
VAR __SHIFTSTART = TIME( 6,0,0 )      -- Provide shift start hour 
VAR __SHIFTEND = TIME( 22,0,0 )       -- Provide shift end hour
VAR __START = Production[Start]
VAR __END =  Production[End]
VAR __PERIOD =  
	FILTER( 
		GENERATESERIES( __START, __END,  1/24/60 ) , 
		VAR __TimeVal = MOD( [Value] , 1 ) RETURN
		NOT WEEKDAY( [Value] , 1) IN {1,7} 		
		&&   __TimeVal >=  __SHIFTSTART  && __TimeVal <=  __SHIFTEND
		&&
           ISEMPTY( 
                FILTER(
                    Breaks,
                    AND( 
                        __TimeVal >= Breaks[Break Start] , __TimeVal <= Breaks[Break End]
                    )
                )
            )		
	) 
VAR __TOTALMIN = COUNTROWS( __PERIOD )
VAR __RESULT = 
    FORMAT( INT( DIVIDE(__TOTALMIN , 60) ) , "00:" ) & FORMAT(  MOD(__TOTALMIN , 60 ) , "00" )
RETURN 
    __RESULT
