C6H5-O-C(CH3)3

This compound is given in my textbook with its trivial name "Phenyl t-butyl ether".
I tried to write its IUPAC name.. but I am getting confused between these 2 names:

1,1-dimethyl 1-phenoxy ethane
and
2-methyl 2-phenoxy propane

Please help! And explain your answer too.

Do you have a diagram?
 
one of your names uses the smaller 'ethane' and the other uses the longest chain, 'propane'. Which do you think is correct?
 
Yeah I know we prefer the longest carbon chain.
But here the main functional group is attached to the 2nd carbon of the chain..
so I got confused..
Does that matter?
 
Nope.
 
Thank you.
