Good morning Bitcoinland.
I see we're bouncing up and down at a rate of close to a grand an hour. Gets dizzying.
Bottom line: a bitcoin is still worth 1000 lakh satoshis.

As for century and epoch nomenclature, I guess it's optional. The first century can also be called century zero.
I guess Century 21 Real Estate established a precedent. It was founded in the 20th century and indeed they originally wanted to name it Twentieth Century Real Estate but thought they'd have trouble registering the name due to it already being taken. Instead of twentieth century, they called it Century 21. They should have called it Century 19 Real Estate though, according to year zero thinking.
Time is relative.
