[Mono-devel-list] Error converting datetime to string

[Rafael Teixeira]

Why should you change the datestyle returned from the database, as it
will be converted to a DateTime, that you'll need to reformat for
display anyway? I think datestyle changes aren't supported.

In portuguese:

Oi Jurandy,  temos que confirmar com o Francisco, mas acho que ele
assume que os dados sempre virão no formato padrão do banco. Como
disse não é legal pedir pro banco fazer uma coisa que você vai
desperdiçar e refazer em seguida.

Grande abraço,

Just the 'crazy' me in a sane world, or would it be the reverse? I dunno...
