NTP and clock config. Confusion about setting time during Daylight time. Really two questions.

I am having trouble getting my clock and NTP config set up right. The NTP
configs are the easy part. I would like to set my clock, but when I set
daylight savings time (EDT) , the NTP client (another router), adjusts the
UTC (Greenwich) to be 5 hours faster than that time. The client routers
always give their time in UTC after synching with their NTP master, which is
a good feature. UTC should only be four hours ahead of EDT, though. Is
that right? I don't think England has Daylight Savings time, does it?
Should I set timezone to EDT and also do the daylight time feature. Will
the router then figure out that it needs to adjust the offset to EST when
daylight time is over, when there is nothing on the router about EST?

I figure that this is one of those things that gets screwed up because I did
something in teh wrong order, kind of like making letting a FR pvc come up
with inverse-arp active before you have gotten your FR cloud configured
perfectly.

Could someone who has run across this same problem share their solution?
Setting up the master router on UTC is not an option. That would make the
situiation much simpler, logically.

A second question:
The Config Guide has a daylight saving time config that merely says
recurring, withoyt specifying the day, week, and time for each changeover.
Does this mean that a standard changeover setting is already built into the
IOS, and the option to set the precise time to first sunday in October (or
whatever) is for folks who live in some place where it is non-standard? It
would nice not to have to memorize the dates for the daylight time
changeovers.
