Hi Martin,
The problem seems to be a fundamental bug in the way that daylight savings is calculated.
Whenever you select a day in the date picker, it seems to select the previous day.
This happens on the live demos, which is defaulted to GMT, as there is no default in trinidad-config.xml.
This then affects validation of the date. ; If we take the example where the date should have a minimum of todays date.
The popup will not allow you to select it, as it calculates that the max day is tomorrow (strangely). I then set the minimum date as today -1. This allows you to then select todays date in the popup, which then selects the previous day.
Eg today = 20/09/2007 (dd/MM/yyyy). Minimum date = 19/09/2007, popup selected = '20/09/2007'
Value returned to text area = 19/09/2007l, which then fails validation - even though the minimum date is set.
It seems like a complex problem with the daylights saving....which i think is coupled with the timezone.

I didn't read very carefully - but this link might be relevant for the issue. Wh at I remember, we were initially using the system timezone for the
f:convertDateTime, but had to change over to using GMT cause else the
TCK would fail under certain circumstances.
