First off, your system date object must not just be a date value; it must also be a date data type. If it is not use the ToDate() function to convert it first. Provided you are working with an actual date you can use the RelativeDate() function twice.

=RelativeDate(RelativeDate([Var System Datetime]; -4; HourPeriod); -30; MinutePeriod)

Alternatively, you could just subtract the total number of minutes.

=RelativeDate([Var System Datetime]; -270; MinutePeriod)
