Training Peaks Date Sync

Hi, when using the app (with a Kickr), the auto upload to training peaks seems to put things on the previous day (so workout done this morning appeared on training peaks as the previous day... the time on the workout was out by an hour or so (daylight savings issue?) but still was on the same day.

Does anyone have any ideas? I've checked that the timezones for TP, iMi and the iPhone are all the same (online and in the various apps).

Not a big deal but it is driving me bonkers!

Workouts uploaded to TP done on a Garmin etc work fine...

Thoughts?
