Andrea, it WORKS. Thank you!
Here is what I found.
I grabbed the geoserver-trunk-2012-02-15-war.zip, unzipped it, copied
the .war file to my tomcat and then via the GUI in the geoserver web
pages connected my time-based layer in Postgres to Geoserver.
When creating the layer in geoserver on the "Data" tab I did NOT create a
Metadata link.
In the new "Dimensions" tab I enabled the "Time" check-box and selected my time
field from my data table.
For Presentation I was initially a little confused, but concluded that the
meanings of the values are these:
"List" - means that on the WMS URL request, the user would provide a list of
comma separated time values like this:
http://localhost:8080/geoserver/wms?VERSION=1.3&bbox=-130.0,42.0,-125.0,47.0&Format=image/png&request=GetMap&layers=xyz:activity_map_r5&width=550&height=250&srs=EPSG:4326&TIME=2012-02-07T03:23:00Z,2012-02-07T04:23:00Z,2012-02-07T05:23:00Z
"Interval and Resolution" - means that the URL request will include a time
interval and a resolution, like this:
http://localhost:8080/geoserver/wms?VERSION=1.3&bbox=-130.0,42.0,-125.0,47.0&Format=image/png&request=GetMap&layers=xyz:activity_map_r5&width=550&height=250&srs=EPSG:4326&TIME=2012-02-07T03:23:00Z/2012-02-07T04:23:00Z/PT60M
"Continuous Interval" - means that the URL request will include a time
interval, like this:
http://localhost:9090/geoserver/wms?VERSION=1.3&bbox=-130.0,42.0,-125.0,47.0&Format=image/png&request=GetMap&layers=xyz:activity_map_r5&width=550&height=250&srs=EPSG:4326&TIME=2012-02-07T03:23:00Z/2012-02-07T04:23:00Z
Note that the WMS 1.1.1 and 1.3.0 (Annex C) specs both describe the kinds of
time data we see here.
I hope these comments help other folks.

I noticed a 2009 posting on this list that indicated WMS access to time-based
data in a Postgres database was not supported.

Has this support been added as of release 2.1.3 ? If so, can someone offer a
sample "MetaData" link file (and the format) that shows how you connected time
to your layer ?
This question has been asked (and answered) just yesterday on this same mailing
list.http://osgeo-org.1560.n6.nabble.com/quot-Time-and-elevation-support-in-GeoServer-quot-td4475438.html
