Same problem with TIMESTAMP, liquibase always converts TIMESTAMP to TIMESTAMP WITH TIME ZONE . Here is how I fixed it. I added a <modifySql> tag to your change set, like below.
<modifySql>
<replace replace="TIMESTAMP WITH TIME ZONE" with="TIMESTAMP WITHOUT TIME ZONE"/>
</modifySql>
Very useful to have this <modifySql> to tweak the ouput SQL generated by LB.
