From the sql
TRUNCATE {$to_prefix}polls;
TRUNCATE {$to_prefix}poll_choices;
TRUNCATE {$to_prefix}log_polls;
---* {$to_prefix}polls
SELECT
p.pid AS id_poll, SUBSTRING(p.question, 1, 255) AS question, p.closed AS voting_locked,
t.uid AS id_member,
IF(p.timeout = 0, 0, p.dateline + p.timeout * 86400) AS expire_time,
SUBSTRING(t.username, 1, 255) AS poster_name
FROM {$from_prefix}polls AS p
LEFT JOIN {$from_prefix}threads AS t ON (t.tid = p.tid);
---*
So it's taking timeout and datline coloumns, which are bigint(30) and appear to be unix timestamps. I have no idea why it is failing as the entry's clearly are int's
example dateline
1094083328
example timeout
1094083328
