On trunk we have full time/elevation support and the mosaic can be
configured to extract the dates from
the filenames and stick them as attribute in the mosaic index, which is
turn used to perform
selections over the time.
Once the attributes are in the index CQL filters can be used, too (in case
you have more than
just the time or have multiple variables and the selection filter is not a
simple equality/range one)
I don't think we have documentation on how to setup time support in a
mosaic though
