Problem in a specification of timestamp

[Joseane Farias Fidalgo <jbf@cin.ufpe.br>]

Hi,

Please: I have to specify a value of timestamp type in the european
format:
"'day.month.year hour:minutes:seconds'" like '01.02.2002 10:20:00'
with the delimiter caracter " ' " delimiting it.
I have tried many things but I only get it without the " ' ".
It compilled and have generated all the packages, but when I tried to
execute it gave an error of parsing, saying that he was expecting a
timestamp value (he doesn't recgnized it). I tried the following:

Thanks in advance, Joseane.
