What do you get when you run i2cdetect -y 0

It should give you a list of devices and their addresses like so:

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: 30 31 32 33 34 35 36 37 -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --                      


Identify the ones you know are connected and the one you cannot identify will be the RTC.

If you are thinking the Omega has an RTC built in, then you are mistaken. You would need to hook one up to the i2c bus to be able to use one.
