tsbox MIT License?

Dependency data.table is fine, but we need a substitute for anytime.

with a bit of luck anytime could become MIT? https://github.com/eddelbuettel/anytime/issues/136 cc @Layalchristine24

@moodymudskipper do we really need this?

AI tells me:

Your MIT license is fine regardless of your dependencies' licenses. The MIT license is one of the most permissive and compatible licenses available. Just make sure to include the MIT license text in your LICENSE or LICENSE.md file and reference it properly in your DESCRIPTION file.

That is also what I said in https://github.com/eddelbuettel/anytime/issues/136. You are not avoiding the gcc compiler or Linux operating system or bash shell ... (I could go on) when you are building this package either. It is irrelevant what license a (reverse or direct) dependee is under: you are authors of a self-contained unit of code, can choose its license and then obey by its obligation. And there is no such (falsely imagined) 'MIT package cannot depend on or use GPL-* package'. You cannot copy GPL code into a MIT-licensed package but that is a very different kettle of fish.

So with that the original assessment above namely

Dependency data.table is fine, but we need a substitute for anytime.

seems not to be relevant. Carry on relicensing as you see fit.

PS Also, of course, R itself. See licence() or license().

So dependencies are not an issue, but we do need the consent of all contributors, even if they authored minor contributions. If they contributed on behalf of an organization it complicates things a bit.

I'll ask for explicit consent below in this thread
For those that don't answer we should send emails
For those that don't answer emails or refuse the change we can either :
- Use dual licensing, with some parts of the code licensed differently, but it sounds like a headache
- Remove their contributions and rewrite them ourselves

Hi everyone,

We are planning to relicense this project from the GNU General Public License (GPL) to the MIT License, to allow for broader use and simpler integration.

Since this project includes contributions from multiple authors, I need explicit permission from each contributor to relicense their contributions under the MIT license. These are currently :

@christophsax @Thu-G-Hoang @maelle ✅ @mbannert @karoliskoncevicius @Layalchristine24 ✅ @will-the-wiz
@krlmlr ✅

If you have contributed code on your own behalf and agree to give permission, please reply to this issue with the following sentence:

"I consent to relicense my contributions to this project under the MIT License."

If you contributed on behalf of an organisation please inform us and if you can't easily get their own written approval we'll find another solution.

The full text of the MIT license can be found here: https://opensource.org/licenses/MIT

If you have any questions or concerns, feel free to raise them here.

Thanks in advance for your help!
