[volt-nuts] Does desoldering and resoldering an LTZ1000A reset the ageing?

There seems to be plenty of evidence that meters like the 3458A improve
stability over time. I believe that most/all is due to improved stability
of the LTZ1000A.

Does anyone know if desoldering one and resoldering resets the aging
process? I see a number of used LTZ1000A ICs on eBay from China that look
like they have been poorly removed. They are about the same price as a
brand new LTZ1000A.

I wondering if properly removed, a used chip is no more stable than a new
