Subject session variable to control timestamp/date format
Author Rafael Kitover

in Oracle it's possible to do something like:

alter session set nls_date_format = ' ... '
alter session set nls_timestamp_format = ' ... '

to set the way dates are displayed as a string for the current session.

Is there something similar for Firebird? I know I can use functions to
format dates, and will do that if there is no other way, but I was
hoping there is a session variable (or 'temporary option' like in
SQLAnywhere) to do this.
