If you do a SHOW CREATE TABLE on the table, you'll see that it has actually ignored your DEFAULT. (What is has done is actually transformed it to '00000000000000', since that is what the string 'NOW()' becomes when you convert it to a TIMESTAMP.) Read this section in the manual for information on how the default value for TIMESTAMP columns is handled: http://dev.mysql.com/doc/mysql/en/TIMESTAMP_pre-4.1.html Support for specifying how TIMESTAMP columns get updated is coming in 4.1.2.
