With the following input:

 Create.Table("MyTable")
   .WithColumn("MyTimeColumn").AsTime()

I would expect MyTimeColumn to be of type TIME. However, it creates a DATETIME column. After looking at the MySql5TypeMap (linking the MySql4TypeMap since that is where the value originates) I assumed this was by design, but after checking out the PostgresTypeMap I now think it may be an oversight.

Thanks for any clarification!
