24 hour wait on International connecting flight because of time-change

I booked a flight with Turkish Airlines for an international flight from Dublin to Entebbe, departing on 1st November 2015. A few months before flying I received emails stating that flight times had been changed for the stop-over flight from Istanbul to Entebbe from 19:15 to 18:15. I had assumed this was because of the time change and did not think it would affect my connecting flight (the clocks changed by 1 hour on 25th October that year).

My flight from Dublin arrived at Istanbul on time and I made my way to check-in for the flight to Entebbe, only to find that it had already left. I asked at the Turkish Airlines desk and they told me it was due to a timing error (presumably because of the time change, she did not give me full details) made by Turkish Airlines and that I would have to wait 24 hours for the next day flight. I was offered hotel accommodation in Istanbul but had to wait for 5 hours before I was taken to the hotel!

I contacted the airline last year and they told me no compensation could be given as they had provided a hotel for the night.

Would there be any form of compensation available, as it seems to have been a system timing error made by the airline? I was never informed that I would not make my connecting flight, with the times on my tickets making it impossible to make it at all!
