How reliable is a vendor's public PGP key creation date?

I grabbed a Hansa vendor's public PGP key on July 10. The vendor's key creation date says some date in 2016, is that reliable enough to assume the key wasn't compromised? Is there a way to fake key creation dates to make them appear older? I received the package ok fyi.

Not reliable at all, you can put any date on your computer and generate key, it will show that key was created in the date which was on your computer. However it is not possible to change it after, date is part of key, different date - different key.
