I mean that somehow I could express getting data in an exact given period of time, say, exactly the day September 11, 2015 in the time zone CET (that day started at 3pm relative to PDT or 11pm relative to UTC). Without time zone support, I would get data “outside” of my desired local time zone. Hope this makes sense and is clear.
A cautious note on time zones...
If you're holding everything in one hour bins, as we currently do with the aggregated data, then it's easy enough to switch from UTC to CET to EST and so forth.
But not all time zones differ by one hour increments. Most noticeably, India is on UTC+5:30, and a handful of other places also differ by 30 minutes from the standard (or in the case of Nepal, 45). I'm not sure you could display these without regenerating the underlying data, which would be a lot of added complexity.
