I added a Maxim DS3231 "extremely accurate I2C real- time clock 
(RTC) with an integrated temperature- compensated crystal 
oscillator (TCXO) and crystal"[1] to my BeagleBone Black based 
Linux system. It appears to lose 1 second every 5 to 10 days, 
which makes it possible to do these modes in the field if the 
clock has been set recently. Since it is a separate board, it 
could be added to many different computers/radios.
