Previously, for timezones w/o tz. The range_end and range_start were defined as UTC, but the constraints on the table were written as as the local time at the time of chunk creation. This does not work well if timezones change over the life of the hypertable. This change removes the dependency on local time for all timestamp partitioning. Namely, the range_start and range_end remain as UTC but the constraints are now always written in UTC too. Since old constraints correctly describe the data currently in the chunks, the update script to handle this change changes range_start and range_end instead of the constraints. Fixes #300.
