Value Of Blur Channels In Python

[kmagill]

Hi,
Sorry if this might be obvious for everybody else. But I'm just starting out in python.
So here's the deal. I want to set my channels value in a Blur node in python, but I can't seem to get a hold on the values.
I created a Blur node and ran a
CODE
print nuke.selectedNode().knob('channels').getValue()

And it gave me a: # Result: 1402912111.0

So I changed to channels in the node from 'all' to 'rgb' and I got the same result back.
So did anyone got this to works?

Thanks.
