Eta Carinae is known to be a "false-supernova". So, they say that it can implode again at any given moment. But, they do not know the age of the star, therefore many others do not know when it will implode again. Now, when do you think a star with 120 solar mass will implode?

It's difficult to predict. From extragalactic "false supernova" events, we know the time between false and true supernova can be extremely short: For SN 2006jc, it was a mere 2 years.
One million years is really an upper limit estimate which assumes Eta Carinae is still at an earlier stage of evolution than the SN 2006jc precursor was.

Hi. When the materials at it's core cannot support the mass above. I would guess much less than 1 million years.
