Hey everyone,
We are trying to create an SLD for a collection of points that styles a particular point differently based on the WMS TIME dimension. In the documentation for SLD parameter substitution (http://docs.geoserver.org/latest/en/user/styling/sld-extensions/substitution.html) there are predefined variables for BBOX, SRS, etc. However, there is not a variable for TIME. Is there currently another way to access this parameter within an SLD?
In org.geoserver.wms.GetMap on lines 496-507 the predefined variables are set using the EnvFunction.setLocalValue() method. Would adding support for TIME (and ELEVATION while we're at it) be as easy as setting "wms_time" just like the other variables?
Thanks,

Yes, that would be the way. However, the time at that point is available as
a parsed java.util.Date object, not in its original form, you can however
use
the Dispatcher.REQUEST thread local to grab it in its string form along with
all the raw request params (in the raw kvp field)
