No bug that I can see. Please be more specific, or the explanation might
be that you have some (understandable) confusion over output date styles
(e.g. 'Postgres', 'ISO') and style hints for both input and output (e.g.
'European', 'US').
Simply setting 'European' will only affect the order of priorities for
interpreting months and days for input parameters when the style is set
to 'ISO' (which specifies the order of fields for dates and times, so is
fixed for output). When the output style is set to 'Postgres' then
'European' also affects the order of output of months and days.
