I have a postgresql database that I deploy scripts to using flyway. I use the maven flyway plugin to launch the database build against the target database. In that build I have scripts that do things like:
create table my_table(
my_date_time timestamp with time zone not null
);
insert into my_table(my_date_time)
select '2000-01-01';
The postgresql database timezone is set to UTC. My client machine (that runs the maven/flyway build) is running CEST (UTC+2:00).
When the scripts run, the database interprets the string literal above as '1999-12-31 22:00:00+00:00' and writes that to storage.
It seems that the jdbc client connection created by flyway is not setting its client timezone to UTC, but is taking the timstamp string and interpreting it as '2000-01-01 00:00:00+02:00'.
How can I set the client timezone on the jdbc connection created by flyway to UTC? Is there a setting that can be placed in my flyway.conf file?
If I change my local machine timezone to UTC the problem goes away, but I'd rather not do that on my development workstation.
A colleague suggested the following
mvn -Duser.timezone=UTC flyway:migrate
