Вероятно виновата база данных. В стандарте SQL (http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt):

There are three classes of datetime data types defined within this
International Standard:

— DATE — contains the <datetime field>s YEAR, MONTH, and DAY;

— TIME — contains the <datetime field>s HOUR, MINUTE, and SECOND;
and

— TIMESTAMP — contains the <datetime field>s YEAR, MONTH, DAY,
HOUR, MINUTE, and SECOND.

Т.е. миллисекунды не хранятся.
