scotpip: I've noticed that when downloading data via Dukascopy web interface with GMT set, there are different times for tick (or S1) and M1 data downloaded before DST change (i.e. in the first part of the year). I asked on Dukascopy forum but received no answer. Have you ever checked? Is it the same for JForex client?

For example:
- AUD/NZD tick data exported for 3.10.2016 start at 23:00 (on 2.10.) with ask price 1.05245
- AUD/NZD M1 data exported for 3.10.2016 start at 00:00 (on 3.10.) with open price 1.05245
