[Chameleon] TimeFilter widget

[Paul Spencer]

The TimeFilter widget is designed specifically to support the TIME 
parameter of WMS requests.  I would expect it is possible for you to 
modify it to support some other type of time based query on postgis 
layers by changing a query on a layer using mapscript.

You could also expose your data through WMS and then use it as is 
(except that mapserver doesn't directly support time yet)

Cheers,

Paul
