timestamp, datetime as default value as current_timestamp [PARTITION]

I have a table column called 'recorddate' where it has timestamp datatype to default CURRENT_TIMESTAMP. Now I have few questions regarding maintenance part.

I should partition this table keeping recorddate as rangekey. But now it wouldn't allow partition key for timezone-dependent expressions in (sub)partitioning function.

If I change the timestamp datatype to datetime for recorddate the partition is created but it won't allow default CURRENT_TIMESTAMP database level.

2.1 . When I see forums stating MySQL 5.6.5 has datetime datatype can have CURRENT_TIMESTAMP, now(). Would it allow rangebykey for partition ? [Another thought that clings on my head is, would it be good to pick a distribution that is still under developement]

Any suggestions or work around, I really don't like the concept of triggers having to be on recordate upon insert if null. As it seeds records almost 5hundered thousands perday and peak time goes to 8 transactions per second on that table. That is the intent of falling on to partitions.

Thanks in advance!! Mannoj
