A gap in Daniel's timeline? Maybe not...

I have heard of the 457 BC date being bandied about before.

I know that the 7th day adventist cult uses that date. That's how their official timeline goes. (457 BC to 1844 AD = 2300 years) They use Daniel 8:14:

New King James Version

14 And he said to me, “For two thousand three hundred days; then the sanctuary shall be cleansed.”

Here is an article on the 457 BC date. Not from the 7th day adventist cult.
