The duration of day will increase because as the ice melts at poles, water will spread away from poles and hence moment of inertia of the Earth will increase.
Since in te absence of external torque angular momentum of the system remains conserved,
So, L = Iω = constant
or, I ( 2 x 22/7) / T = constant
or I is directly proportional to T
If I increases, T i.e. duration of day will increase.
