I have already tried all possible timestamps for 32 BTC Puzzle with this method from
start_datetime = datetime(2010, 1, 1, 0, 0, 0)
end_datetime = datetime(2015, 1, 15, 19, 7, 14)
unfortunately, this puzzle was not created with that tool.

But you can try all other BTC addresses that have a positive balance using the same method.
Good luck.
I am still working to implement math.random() as it was used in the older version of browsers.
Chrome and Firefox had slightly different methods.
