I live between Balto. & Wash. DC and was fortunate enough to meet Nate at OH/DC then I assisted at the National Electronics Museum booth on Sat & Sun at USASEF. I could see the Sparkfun booth and the throngs of people talking to the Sparkfun folks and waiting patiently for the soldering school. How many burgeoning hackers did you run through there? Great job Sparkfun!

I sent an email to MAXIM support and got the following reply:
Our I2C clocks are all set for D0h, and there is no way to change that, except on the DS1372 (32-bit binary counter), where you can place 2 devices.
The DS3234 uses SPI communications, which usually requires device-specific Chip Enable inputs from the Master. There is no Slave Address in SPI.
DS3231 and DS3232 are I2C-formatted TCXOs.
Alternatively, you might add an I2C mux to place multiple components of the same Slave address.
I want to connect several RTC's at once. Is there a way to change the slave address on a DS1307 and DS3234?

Sorry, I wasn't pay attention to what I was reading. 2 seconds in 11.57 days = 1 second in 23.14 days, therefore my math does agree with your numbers. Can I chalk it up to a long day?
My math comes up with different numbers. +/-2ppm = 2E6, there are 60 sec/min, 3600 sec/hr and 86400 sec/day. 2E6 divided by 86400 sec = 23.148148 Days. Therefore if the error remained constant at plus or minus 2ppm it would take 23 days, 3 hrs, 33 min and 20 sec to gain or loose 1 sec repectively.
No public wish lists :(
