This is the latest instalment of the Arduino saga! The Arduino is used to drive an LCD controlled with a PCF8574 IO expander and a DS1803 dual digital pot. It also communicates with the DS1337 RTC. The time is set by sending a unix time stamp over serial. The Arduino does all the gmt offset and dst calculation!

Is the "I/O expander" a shift register? You need a Boarduino! Nice project...

No, it's a PCF8574 I2C bidirectional IO expander. Everything on there is (the temp sensor has been changed to a ds1624 I2C 13-bit temp sensor). Yes I wished I had one indeed! Thanks :)
