Wrong month labels

My SQL query produces a table like this:

The “month” column is made like this in the query:
DATE_FORMAT(payments_table.create_time, '%Y-%m') AS 'month'

But when I visualize it as a bar chart, I get this:

As you can see, Metabase is labelling “2016-04” as “March 2016” when it should actually be "April 2016"

Can I fix this myself or is this a Metabase bug?

This looks like it’s the same thing as https://github.com/metabase/metabase/issues/2340

Ok. However changing Metabase “Report Timezone” apparently changes nothing here.
