Incorrect parameters in [time] shortcode in Make posts show wrong dates

[joyously]

Several of the posts on Make blogs use the [time] shortcode incorrectly, so the dates that are shown are not useful.
The ones I saw that prompted this ticket are all visible on ​https://make.wordpress.org/core/tag/new-contributors/
although I'm sure there are others in other Make blogs, perhaps on their meeting summary posts.

Are there any specific examples to check against by any chance? How are they used incorrectly?

Well, each post has a link for Next Meeting.
The post from Sept 1, 2017 says next meeting is Sept 12, 2018. I doubt that is correct.
The post from Aug 17, 2017 says next meeting is Aug 1, 2018. That can't be right either.

My assumption is that the relative parameter is what is wrong, but it could be a bug in the shortcode.

The time shortcode is [time relative]Wednesday, September 6, 19:00 UTC[/time] which does indeed mean it'll be relative to todays date, rather than the posts.

I've updated it on ​https://make.wordpress.org/core/2017/09/01/new-contributors-meeting-recap-august-30th/ to not include the relative param, which seems to have fixed it for that post - I can't go through all of the posts though

Let's educate authors rather than having us chase down every single instance of misused shortcodes.
