This little Black Duck is struggling to write a simple spreadsheet calculation for flight itineraries that does several things, including adding a flight time to a departure time and date and automatically changing the arrival date if it clicks over.
Say depart field/cell (12/09/07 23:30) flight time field/cell 4:30 returns = arr 13/09/07 0400. Then have the ability to add/subtract a time zone change to the resultant.
Any genii out there who can help me.
