Thanks, I've come up with this expression, then:
to_char(date, 'YYYY-MM-DD')
|| 'T'
|| to_char(date, 'HH24:MI:SS')
|| to_char(extract('timezone_hour' from date),'S00')
||':'
|| to_char(extract('timezone_minute' from date),'FM00')
This form is typically used in datetime fields in xml files, and
somehow I was expecting a pre-existing format for it, such as php5's
date("c") rather than the complex expression above :)
