 I thin kthe rcm script can do this for you.

  But what it does is create a link from /etc/localtime to 
/usr/share/zoneinfo/GB

i.e. ln -s /usr/share/zoneinfo/GB /etc/localtime

  This takes care of summertime for you. I didn't know you could do this 
under RiscOS too!  I've been running with my RiscOS clock in GMT (i.e. 1 
hour behind) all summer!

As to setting the clock, 

man date
man rdate  (this one's particularly useful)

Ale.
