Why not 11:59 and 59 seconds, that'd make more sense!. I would mean that person is ready to have kids!.Www@QuestionHome@Com

it means that she is getting too old to have children!. given the context, she may what to have a child!.

the timing refers to the nuclear winter clock!. according to politics in the cold war, then the time reaches midnight, the nukes go off and the world ends!. dooms day clock, you know!.Www@QuestionHome@Com

I'd say it probably means the person's ability to have children is almost over!.
