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

Question

How do you set the default value of a date column to be \"now\" in UTC format? I think the answer involves the defaultValueComputed attribute on the column elem

Answer 1

In MySQL, to use a DATETIME column with fractions of second like DATETIME(6) (microseconds precision), use default value of NOW(6) (caution: CURRENT_TIMESTAMP(6) for some reason produces an error with me using liquibase 3.5.3):

Note that the value will be stored internally in UTC, but read using the server's timezone settings (@@global.time_zone, @@session.time_zone).
