Crystal Reports Converting Seconds to Minutes

Message

     Trying to get a more precise formula for this. Currently am using this: 

whileprintingrecords;
NumberVar Days    := Truncate (global numbervar nIReady / 86400);
NumberVar Hours   := Truncate (Remainder (global numbervar nIReady , 86400) / 3600);
NumberVar Minutes := Truncate (Remainder (global numbervar nIReady , 3600) / 60);
NumberVar Seconds := Remainder (global numbervar nIReady , 60) ;
if nIReady=0
    then 0
        else
(Days*1440)+(Hours*60) + Minutes + (Seconds/60)

Is there a better way of doing this? Seems like I'm getting some numbers that are a bit off with the current formula.

Thanks.
