There's a WFS I'm accessing via script to pull in features that will match a particular day. The attribute I care about in the output is DATE_TIME. However because it's WFS 1.1.0 it does not support temporal CQL queries (per the GeoServer documentation anyway).
The DATE_TIME values are stored in ISO format, YYYY-MM-DDTHH:mm:ss. I would like to issue a CQL query that will return only rows matching a wild-carded day or month, but have been unable to find examples of this kind of thing that will work with 1.1.0:
/ogc/wfsServer?service=WFS&request=GetFeature&typename=[name]&version=1.1.0&propertyname=DATETIME,EVENT,DESCRIPTION,ETC&[put CQL here to do ONLY RETURN ROWS WHERE DATETIME=2017-01-01%]&maxFeatures=1000&outputFormat=application/json
Not looking for my homework to be done for me - If there is a reference page with examples on this, would be happy for a link, as I haven't turned up anything by googling.
