need formula to add minutes to date

Look at this thread: Variance calculation

Especially Dave’s sample code should be a good starting point:

=((( (ToNumber(SubStr(FormatDate(<DATE2> ,"HH:MM:SS") ,1 ,2))*60*60) + 
(ToNumber(SubStr(FormatDate(<DATE2> ,"HH:MM:SS"), 4, 2))* 60) + 
ToNumber(SubStr(FormatDate(<DATE2> ,"HH:MM:SS"), 7, 2))) - ( 
(ToNumber(SubStr(FormatDate(<DATE1> ,"HH:MM:SS") ,1 ,2))*60*60) + 
(ToNumber(SubStr(FormatDate(<DATE1> ,"HH:MM:SS"), 4, 2))* 60) + 
ToNumber(SubStr(FormatDate(<DATE1> ,"HH:MM:SS"), 7, 2)))) / 3600) + 
(DaysBetween(<DATE1> ,<DATE2>)*24)

I believe there is also a DLL one of the BOB members wrote which allows adding time.
