why was all the datetime fields switched to int without migr

[gnewtzie]

my question is why was the datetime field changed to int and the data wasn't migrated? I upgraded from 1.1.8 to 1.2.3 and had to run the database scripts manually. After the upgrade all the last updated fields are 1969-12-31. Why would you create the new field, drop the old constraints and field then rename it without migrating the data over? This pretty much stops me from ever upgrading the actual instance to any new version.

The data is migrated. There is a function install_date_migrate which is called during update when using admin/install.php
