PDO::setAttribute() to control formatting of date/timestamp columns:
PDO::FB_ATTR_DATE_FORMAT, PDO::FB_ATTR_TIME_FORMAT and
PDO::FB_ATTR_TIMESTAMP_FORMAT. These attributes are strftime
format strings, and operate in the same way as the ibase.dateformat,
ibase.timeformat and ibase.timestampformat ini options.
