You could report it to the seller as a fault. He must have quite a bit of
experience on these.

Another option would be to hack the ntp software so it gives out a correct
date, assuming that you can determine what the

I think you should contact the seller.  Let us know how he responds.  I
hear good and bad things about him. It is quite possible that there is a
team of people,  rather than one person, so maybe it varies a bit.

I have just bought an 58503A from him. This is not an upgraded one, but
should be a unmodified 58503A. I only bought it in the last few hours and
are awaiting the invoice.

I will let you know what that is like.

The term "upgraded" can be interpreted different ways. It doesn't mean it
has to be 100% identical in every way.
