Well... pseudo science does have a long history. This 1939 essay by Alexander Phillips is just one in a long line.
The nice part about this one is the events described are very commonplace: Two English ladies while walking through Versailles walk back into time from 1901 to 1789 for a few minutes, talk to a few people while getting directions, then walk back into 1901 and continue their tour. They don't notice anything strange until they check their mental notes after they finish their outing. We are time traveling but not changing history or dealing with famous events and people.
Much of the essay is about how these ladies double checked their memories against recorded facts about Versailles physical layout one hundred years earlier, and the clothing they saw. The ladies, and Phillips, have gone to a lot of trouble to dig up obscure facts that support their claim.
There are two technofiction problems I have with this recounting.
o First, there is no mention of archaic French being spoken by the people they talked to, and there were several. The essay makes a point that one of the ladies spoke French quite well, and this odd language usage would have started "strange" bells ringing instantly for her at least. As a contemporary example of hundred year old usage, imagine talking to young Laurel and Hardy and not noticing anything peculiar about their speech. These people they met may not have acted any differently, but they would have noticed this speech difference first-off.
o Second, even in the gardens of Versailles you can see background that is blocks away. These ladies describe the walking into and out of the time-slip as being unnoticeable at the time. It's not clear how these ladies could slip in and out of the past without noticing changes in the blocks away background. Trees, for instance, may seem unchanging, but they change, and these two ladies had their heads up, they were looking for the right path in a strange place.
So... fun but not profound pseudo science. The other interesting part is how often Phillips uses adverbs such as "absolutely" and "precisely". For me this is a signal that pseudo science is threatening. In real science things can be fuzzy, there can be some "maybe"'s.
Update: Here is the current information on the incident in Wikipedia: http://en.wikipedia.org/wiki/Moberly%E2%80%93Jourdain_incident. The mundane explanation listed there is that they got lost, stumbled into a period costume party being held on neighboring grounds, and were told how to get back to their destination on the Versailles grounds.
