Kan man ikke sætte NOT NULL på timestamp?

snuppet fra manualen:

In MySQL, as in many other SQL servers, you can't index columns that can have NULL values.  You must declare such columns NOT NULL. Conversely, you cannot insert NULL into an indexed column.

When reading data with LOAD DATA INFILE, empty columns are updated with ''. If you want a NULL value in a column, you should use \N in the text file. The literal word 'NULL' may also be used under some circumstances.  See LOAD DATA.

When using ORDER BY, NULL values are presented first. If you sort in descending order using DESC, NULL values are presented last.  When using GROUP BY, all NULL values are regarded as equal.

To help with NULL handling, you can use the IS NULL and IS NOT NULL operators and the IFNULL() function.

For some column types, NULL values are handled specially.  If you insert NULL into the first TIMESTAMP column of a table, the current date and time is inserted.  If you insert NULL into an AUTO_INCREMENT column, the next number in the sequence is inserted.

Ok - men jeg får jo ikke helt svar på mit spm. Jeg får at vide, at dato osv indsættes, hvis jeg ikke selv indsætter noget i feltet. Men hvis jeg har brugt NOT NULL da jeg oprettede tabellen, hvorfor står der så i PHPmyAdmin, at den netop er NULL ?

takker for point :-)

Det' mig der takker :)
