Hey!
Changing the timezone to GMT did indeed fix the import errors and the parse error!
However the times and dates are still being imported incorrectly.
Facebook event:

and on the website in event panel:

All of the events start and finish at the same local time regardless, so a blanket change of all events to say start at 8am and finish and say 6pm would be awesome, then its just the date being reported wrong.
Many thanks!
