Native timezone handling of Daylight Savings Time during timezone conversion would be beneficial to me as well. I am charting purchases by hour, and the hour of the day obviously is not going to convert properly year-round with a simple offset against a date column that is stored in UTC. My target db is MySQL and I realize that MySQL does support timezone conversions IF the timezone table data has been loaded by the DBA. It has not in my case, and the quick workaround would have been for me to take care of this in PowerQuery.
