Thanks Pascal... The application I implemented is to follow command made by our client... and it's needed to display all the information of the date (timestamp format) saved on database ...
We have some people working in Maroc and it's them that encountered 'the problem' ... I thought that to force the locale of the application in the .gwt.xml and in the jsp page with the meta line, will resolve the problem... it seems that its the case on my computer.. but not when i deploy the application ! Not easy to manipulate date in informatic ! JP On Feb 12, 8:54 pm, Pascal <zig...@gmail.com> wrote: > Bonjour JP, > The problem is not with the DateTimeFormat class.
