Silly Question: Why is the default date 2488-10-12?

The default value returned from a datetime variable is ‘2488-10-12 16:06’. My initial thought was that this must be significant in the timeline of some film or television programme but I’m unable to find anything.

So, why is this is the default datetime value?

Birth date of Tim Sweeney.

Yup he is the true time traveller.

Or look into source code of that function.

Mighty forum contributor, any chance you lend me some help with my issue? :3
