I can't think of an easy native way to make this happen but perhaps something could be worked up in SQL as a trigger perhaps that would apply the conversion to the relevant cells. I found this article on how to recast a hex value as a datetime within SQL.
Definitely getting into murky territory but it's doable. I also created a feature request for Solarwinds to handle this natively if you want to vote it up

I will try to work around it if snmp get is not useful...
Is there cli or netconf that will give you that date?
if not I will just run NCM job or what ever you use to use to schedule that rescue disk backups
