time series problem 3 (Bug!?)

[Jeroen Ticheler]

Hi, sorry for continuing this story, but I really want to solve this  
and hope my additional info helps to sort out the problems I face.

I am using a shapefile with the imgdate column added to it. I use  
exactly the same index to work with a WCS on the same data, that one  
works perfectly fine.

I have browsed through the mapServer sourcecode to see if I could  
discover something/ understand the problem better. I'm not familiar  
with C coding, so forgive my ignorance :-) What I could understand is  
that my request fails when the time string submitted in the request  
is compared to the timeextent given in the capabilities document.

The exact section of the code is in  between line 545 and line 569,  
apparently the msValidateTimeValue() procedure fails to find the  
requested date in the extent. I do not get an error when I change my  
extent to a range like "2005-09-11,2005-09-21/2005-09-21" or  
"2005-09-11,2005-09-11/2005-09-21", but it will only render the very  
last image, even when an earlier one is requested.

So I guess I face a bug!?

Thanks again,
Jeroen
