Update MetaData.cpp

[JoseFC3000]

I think is better don't to shot 'unknow' when no info in those fields. This is anoying especially when you are in Favorites and no games in in the list and you see 'Unknown' in the fields

TimeUtil.cpp compares with "not-a-date-time" string value - unsure if there are other scenarios where this type of change may break other things. Please assess or at least address this impact if possible.

Thanks @JoseFC3000 for sending this over, and thank you for putting in the time and effort of making this recommendation.

I added some comments about the impact of this change that would need to be addressed, but more than that, I want to share some context on where I'm at with this proposal. I agree that this is very much a personal preference topic, and precisely because of that I am not confident that this change should be incorporated without further thought or validation. The fact is that this has been around in ES for ages, and no complaints have ever emerged about it.

I personally don't feel strongly one way or another (maybe other project members will), but the fact that this has long been accepted as the expected behavior may end up making a lot of users voice their preferences the other way around, turning this to a context of "who speaks the loudest".

May I ask if you have run this proposal by the forums, specifically in the "Ideas and Development" section, and see if you get some critical mass of people commenting about whether they agree with you that this would be indeed a clear improvement, and whether there'd be any existing theme where such a change would break the expected look and feel, for instance?

Getting some data here could help facilitate a decision on this but, unless someone else from the project has a strong preference one way or the other, my preference will be to hold out on this until we find that this is something that should indeed become the new default. If you already have such feedback, then please share it - thanks!

Hope this clarifies the lack of movement on this PR, and as I was reviewing some these past few days I thought it'd be fair to at least share a possible way forward.

Best.
