Bug !? Date selector picks up the wrong Date

Hi

I developed a Web Dynpro application which also have a imput field. The context that is mapped to it is a Date type. Sofar everything is ok. If I either select a date or enter it manually the date is shown right in the Inputfield. But as I want to get the Context like:

pStartDateOrig = wdContext.currentContextElement().getCtx_startDate();

, the Value is wrong. When I entered i.e. 07/25/2005, the debug mode shows me a value of 07-24-2005. That value is than stored wrong during the further processing. That bug does not appear permanently. Have anyone an idea? Is that a known bug. Any comments are welcome.
