RSS suitable for date/time relative material ?

[Simon Fell <soap@zaks.demon.co.uk>]

Hi,

I've been looking at RSS to see if its suitable for syndicating
information about time relative content, i.e. Live audio/video webcast
streams. There doesn't appear to be any structured way to include the
date/time info, which has lead me in the direction of putting the
date/times in the <title> and then either each night generating a new
list of what's coming up tomorrow, or adding items a few hours before
they start.
A few questions
1. Is RSS the best approach for this, is there some other standard
that would suit it better ?
2.Is my assumption on handling date/times in RSS correct ?

TIA
Simon
