for upward,
h  = uT1 – 0.5gT1^2................(1)
for downward,
h = 0 + 0.5gT2^2..........(2)
comparing  both the eqns.
it seems,
h is more for 2nd eqn.
therfore T2 would be more. for downward time.

Dear Vikas,
 U should also consider ‘Air Drag’.
 the way us solve the solution is seems like the general sase of free falling.
 and in free falling case both T1 and T2 Are same.
 And there is dependency of time and Distance.(Distance is just a comparing Quantity.)
