You might be interested in reading chapter 7 of the "Beginning Google
Maps Applications with PHP and Ajax" book, where they explain the basic
technology that is used for doing this sort of thing.
In the book, they consider how to display the locations of over 115,000
radio masts in the USA, and come up with this:
http://googlemapsbook.com/chapter7/ServerCustomTiles/
In the book, they also explain how to handle clicks on the locations,
but that feature is not present in that example.
The book was written back in 2006, before there were
GTileLayerOverlay()s, but the basic principle is the same.
The only extra bit that you really need is to add your time information
to the request that gets sent to the server, and have the server include
those criteria when it selects data from its database to be painted on
the tiles.
Instead of having "From" and "Till" fields in the request, I'd suggest
having a target moment field and a +/- amount. The server could paint
larger icons for items that are closest to the target moment, in the
same way that the Google GLayers paint larger icons for items that have
a higher popularity rank. About two large icons per 256x256 tile is
reasonable.
