I was looking for space requirement for "TIMESTAMP" datatype. Looked in "Oracle Database SQL Reference" but didn't get anything about space usage.

STFW pointed to this website http://www.devarticles.com/c/a/Oracl...n-Oracle-9i/1/ which says 7 to 11 bytes. But I wanted the exact requirement from Oracle docs. Can anyone please point me to correct doc?
