Copyright timespan needs update

In the following line

https://github.com/edubart/nelua-lang/blob/dc479bf4b1ad1335d9caa6cdbf282cc5979f06c0/lualib/nelua/runner.lua#L44

the year remained at 2022.

Do you need it to get updated or should you remove it and leave it as console.info('Copyright (C) Eduardo Bart (https://nelua.io/)') ?

At first, I was thinking something like console.info('Copyright (C) 2019-' .. os.date('%Y') ..' Eduardo Bart (https://nelua.io/)') but then I asked myself, is it really necessary to have a copyright timespan?

I've updated the copyright year in https://github.com/edubart/nelua-lang/commit/58a189d794d9c2be51c970a434f2f6fd13bd88ac using your suggestion, but with a minimum year (in case the system clock is skewed).

is it really necessary to have a copyright timespan?

I think that according to some law, a copyright has life time that eventually ends, it does not hold forever. Imagine we are thousands years in the future and someone wants to use this very old code, since the copyright may have ended centuries ago, the code will be in public domain and the copyright will have no meaning anymore. I think that to hold copyright forever, we have to effectively keep updating the copyright year forever. I am not sure if it works really this way, but that is what I've always assumed.

I have completely forgot about the legal obstacles various countries put on us developers.

Thank you for reminding me that!
