Hey all,
The clock on my 2003 LS sets automatically from from the GPS after you use the setup menu to tell it your time zone and turn daylight savings time (DST) on or off.
My IS F also has a nav system, but the clock does not set automatically to the GPS. The setup menu allows you to set the time zone and turn the DST on / off, but these settings have no effect on the clock.
the time setup is for estimation of your arrival time when you use the Navi. That cheap clock in the 65,000$ car is just that. A cheap clock. Yeah both of my IS-F's clocks were set by me and not the computer/GPS. I too was hoping for something a bit more refined. In the pursuit for perfection Lexus needs to start with the clock in the IS-F.

What year is your IS-F? My 2007 RX doesnt update the time on the right dates. Its because of our great congress. They changed the start and stop dates. But the car computers didnt change.
In 2005 and 2006, Daylight Saving Time begins for most of the United States at 2 a.m. on the first Sunday of April. Time reverts to standard time at 2 a.m. on the last Sunday of October.

The new start and stop dates were set in the Energy Policy Act of 2005.
