Liquibase: How to set the default value of a date column to be “now” in UTC format?

Maybe this topic in the liquibase forum will help?

I think defaultValueComputed will take a database specific function to express “now”. In mySQL it would be CURRENT_TIMESTAMP so it could look like this:

<createTable tableName="D_UserSession">
    <column name="ts" type="TIMESTAMP" defaultValueComputed="CURRENT_TIMESTAMP"/>
</createTable>
