[development] PDO question

I'm having problems with a database field which is type 'datetime' in a Drupal 7 install, using alpha7. It installed OK a few months ago but now causes the module install to crash, it would appear that the datetime type is no longer supported or this is a bug in the PDO Database Abstraction Layer. I notice that core modules using timestamp fields are using type 'int', should I do the same? I am reluctant to do this as it will make upgrades from D6 just that much more difficult, I am testing this on Ubuntu 10.04, fully up to date. -- ----------------- Bob Hutchinson Midwales dot com -----------------
