I am trying to migrate several years of historical data with timestamps
from an MS Access database to Postgres. I am running into an issue where
specific dates/times get pushed one hour ahead, which creates duplicate
date/time stamps or failes the import if I have that defined as my
primary key. The time that gets shifted is always 2:00 AM to 2:55 AM
(data is in 5 minute blocks). What I don't understand is that it only
seems to happen on the following dates (m/d/yy format):
4/7/02
4/6/03
4/4/04
4/3/05
4/2/06

Daylight savings time shift?
