I've created task using web interface and set due date as today and time e.g. 5pm. Then I've synced this task with my Android. And its due time on android is 4pm. I have no idea why. If due time is not set at all this causes that due dates differs by one day.

I tried to change Timezones on both sides but this doesn't affect at all. The difference always is exact 1 hour. I believe that the cause is Daylight saving time settings. Does anyone have the same issue? I lost hope to get an answer from support. They ignore my support requests. So maybe anybody of RTM users can help me?
