It looks like you are expecting the address of the struct passed to your 
function but not using the address in the function.  Try it this way:

void CalculateOffTime(uint8_t duration, offTimeStruct eventOff)
{
    ...
}


Also, I think the typedef is wrong.  Try it this way:

typedef struct
{
	uint8_t endMinute;
	uint8_t endHour;
} offTimeStruct;
