Every samaya, a single hair-tip is removed from the cylindrical pit. The total period of time that elapses for emptying it completely is called bādara uddhāra palyopama. It is actually only formal palyopama, because its value is under countable time units.
Removing a single hair-tip each samaya, the cylindrical pit will get emptied in 3.3 x 1036 samayas. So we come to the conclusion that one bādara uddhāra palyopama = 3.3 x 1036 samayas.
