Richard, I would second the desire to make QGIS more timezone aware. QDateTime supports time zones so QGIS does support it, but not much effort has gone into really supporting it. I currently have a task to do a QGIS date/time conversion tool with algorithms to convert between different time formats including EPOCH time. This was something that I was planning on starting soon. Like you said though time zones are going to be a real pain especially if you want to take a coordinate and convert it to a time zone. There are some python libraries I have been investigating to help with the task.
