[@YungTweak] The setting has many anachronisms making it difficult to discern an exact year, if one even exists, but it's mostly based on the 50's and early 60's. Probity's conservatism makes them look and act like it's the 50's, but outsiders from Probity would probably look and act like it's the 70's. Both of them have computers from the 80's, and the soundtrack could go as far forward as the 90's.
