Without + this change, timestamptzs are read as localtimes and saved as + localtimes, when they should be read and printed as UTC times, + this bug will lead to dates changing every save as they are being + reconverted to UTC again. + + We followed a minimal approach (following postgresql' lead), we + simply add a is-utc? boolean. Before this, zoned times were + converted to UTC, but since we never tracked that it was a UTC + time vs a zoneless time, there was conflation between the two. In + order to preserver comparability between dates and times that are + local vs UTC. I wrote a `time-to-utc` utilizing decode-time's + implementation dependent timezone defaulting. + (I verified the math by comparing results to the local-time + library from quicklisp). + + Ultimately, adoption of a third party datetime library is my + strong preference (eg: local-time). While this project has, as a + whole refrained from outside requirements, I think that we should + consider moving to local-time as our date / time format, or + providing that as an option, both to support a semi standardized + eco system, and also to have a more robust timestamp implementation. + + 2016-01-26 Kevin Rosenberg * Version 6.7.0 release * sql/utils.lisp: Apply patch from Martin Simmons for
