OK, I mentioned to @tomhughes last week that I feared this might be the case and that it needs more investigation. From my initial investigations it appears that there isn't a version of `to_char` that takes `timestampz`, so it is most likely converting `timestampz` to `timestamp` and then doing the character formatting.
> I think we would have to add `at time zone 'UTC'` to all statements for a correct timestamp then. This change however needs to be exactly in sync with changing the column type to "timestamp with time zone" to avoid incorrect timestamps on a non-UTC system.
If there's a way to avoid the synchronous changes, that would be worth looking into. For example, cgimap could try column type detection, or we can find a different time formatting function, or so on. Basically we should try to come up with a solution that allows cgimap to work with both timestamp and timestampz columns interchangeably.
