This is not really Linux based, but I guess it may be.

I have this fleeting idea that possibly you could use a master clock to blue-tooth connect to all your other clocks and reset date/time/alarm info/etc when a power outage knocks out all your clocks or you have to reset for daylight savings time. The key to all this is irig-b, and my test platform would probably be my laptop.

So I was wondering if there were any links to the irig-b, irig-a formats. Hell, even the irig-c may be a good source.
