Whats with the time differance

Booked on VS 75 MAN-MCO on Sunday 28th Oct. For some reason the flight doesn't arrive MCO until 15:50, 75 minutes longer than the usual flight. [:0]
My first thought was that it was something to do with altering the clocks but I then found out that the flight is also scheduled to arrive at 15:50 on Thu 1st Nov through to Sat 3rd Nov of the following week.
Anyone got any ideas what the reason is? [:?]
Thanks in anticipation.
