no create/update time for InnoDB from SHOW TABLE STATUS?

It looks as though, when I go into my databases, and use the command  
"SHOW TABLE STATUS", that InnoDB tables do not have some information.

I am on MySQL 4.1.0-alpha-debug. Has this been fixed in later versions?

Example:

mysql> show table status;

2 rows in set (2.78 sec)

Notice the "Create_time" and "Update_time" data is NULL.

Any reason?
