Thanks, Jeff and all for the suggestions (assuming this works, as it seems it should, I may go with this one). I'll try them tomorrow. After posting my query, I discovered a related problem which I have to research more, but perhaps someone here knows what is standardly done. As I said, I have one dataset that stays in standard time to avoid the DST issue. I have to merge() it with another that uses local time. In the spring, there are thus no datapoints from 1:59 until 3. I'm not yet sure what happens in the fall. Is there a best practice for dealing with periodic (hourly, quarter-hourly, etc.) data that spans the DST change such that graphs of time series, etc., are easily understood?
