Pretty simple, I need to disable time zone conversion for specific columns. I will handle any TZ conversion manually, but I need Rails 3 to forego conversion in both writing and reading, and any AREL functions. But, I don't want to disable the conversion for non-specified attributes.
Ok, I know how to disable it for reading:
self.skip_time_zone_conversion_for_attributes = [:test_timestamp]
But this only works for reading. When writing the attribute, it still converts to UTC (yes, I tested this in 3.2.8).
