When Does "The Time Machine" (1895) Take Place?

"The Time Machine: An Invention" is a science fiction serialized (partwork) novel written by H.G. Wells that premiered January 1895. So when is "The Time Machine" set? 


It takes place in the year: 

802701 AD 

We know this because soon after the unnamed Time Traveler arrives in the future, he narrates to us: "I resolved to mount to the summit of a crest, possibly a mile and a half away, from which I could get a wider view of this our planet in the year 802,701, A. D. For that, I should explain, was the date the little dials of my machine recorded." Assuming his machine's instruments are accurate it is the year 802701 AD. 

Additionally, there are opening and closing scenes that take place in the Time Traveler's home time that form a frame-narrative. At one point in the year 802701 AD, the Time Traveler specifically says, "some Eight Hundred Thousand Years hence", certainly referring to his 'the present'. That would put the Time Traveler's home time as roughly like 2701 AD. 

802,701 - 800,000 = 2,701. 

HOWEVER, during the opening the Time Traveler says, "Professor Simon Newcomb was expounding this to the New York Mathematical Society only a month or so ago." The real-world mathematician Simon Newcomb (1835-1909) lived from March 12th, 1835 AD to July 11th, 1909 AD. So it must be before July of 1909 AD during the prologue. 

Finally, there's chapter 14 "The Further Vision" in which the Time Traveler declares he pushed "more than thirty million years hence". So it's something like 30001900 AD. 

1,900 + 30,000,000 = 30,001,900. 

It was adapted to audio-drama in 1948 and again (with the same script) in 1950, then to comics in 1956, to film in 1960, then in a 1960 comic-book (mostly adapted from the film of the same year), somewhat loosely into a TV movie in 1978, a comic-book mini-series in 1990, to a new audio-drama in 1997, to film again in 2002, and then to audio-drama again in 2009, as a graphic novel in 2010, and finally as another audio-drama in 2017.
