The select returns a timestamp in UTC, not in localtime. If you want localtime
you need to specify that:
SELECT datetime('2012-05-06T18:57:41-01:00', 'localtime');
or do you mean something like
SELECT strftime('%s', '2012-05-06T18:57:41-01:00');
which returns the number of seconds since the unixepoch?
