That makes a lot more sense now, although I'm not sure why it is only happening in the spring and not in the fall. The original data field is a MS Access "General Date". In Postgres it is stored as a timestamp with timezone. To do the import, I tried using an Access append query. I've also tried to use the Access export function. Reading up on Windows XP handling of DST, it appears that it is unreliable for pre-2007 time shifts, which would explain why it isn't happening with more recent data. Is there any way to ignore DST in an import/export transaction?
