Most of us have figured the HP stories as being in the early/mid '90s,
since the deathday party in CoS gave the date of Nick's death, 500 years
before, as 1492.
 However, in GoF Harry mentions Dudley throwing his Playstation out
 the window; this is highly unlikely if it's 1994, and the PS wasn't
 available until 1996 or '97.
 Also, remember the part in P/SS with the Dumbledore Famous Wizard
 card? When he's said to have "defeat(ed) the evil wizard Grindelwald in
 1945", I get the distinct notion JKR expects us to think Dumbledore spent
 roughly the WWII period dealing with this guy (note the Germanic-sounding
 name).
 I've heard great things about these "lives". I really must get one. :)
