Tom,
I think that should work. I checked a bit the code and It should not be
too bad to integrate. You should post it as an enhancement for sure.

Assefa,
Thanks for the info. What about doing it like this:
- WFS filter is sent
- mapwfs.c checks mapfile to see if LAYER/METADATA/"ows_timefield" matches
Property element
- if yes, do a time-enabled expression
- if no, do a literal expression as per usual
Comments?

Tom,
This end up to be setting the expression as It was a litteral
expression instead of setting it using the back tics that indicates to
mapserver to do time comparing (`[time_field]` ge `2004-10-12`). There
is no detection right now to see if the filer parameters are time values
or not. Not even sure how we should detect it. If we can find a way or
logic to indicate that the value is a time, setting the filter is pretty
easy.

Hi,
I'd like to do a GetFeature request, something like:
http://devgeo.cciw.ca/cgi-bin/mapserv/ecows?service=WFS&version=1.0.0&request=GetFeature&typename=obs&filter=<Filter><PropertyIsGreaterThan><Property>datetime</Property><Literal>2002-10-30T00:00:00Z</Literal></PropertyIsGreaterThan></Filter>
The result should bring back two results (i.e. more recent than 2002), but
returned are all the records. The data is configured for WMS Time support.
Is it possible to do temporal slices in MapServer WFS in this fashion?
