Anyone?

The number 2147483647 consistently appears in all clips that do not seem to include a year in the timestamp.

Fascinatingly this number is one of only “four known double Mersenne primes” –

https://en.wikipedia.org/wiki/2147483647

Further down in the wiki under “computing” it notes:

“The number 2,147,483,647 is also the maximum value for a 32-bit signed integer in computing. It is therefore the maximum value for variables declared as int in many programming languages running on popular computers, and the maximum possible score, money etc. for many video games. The appearance of the number often reflects an error, overflow condition, or missing value.[8]”

… which probably answers my question. Although I’m not entirely sure why this would be the case if I’m running a 64bit kernel with Mavericks.
