I'll have to remind myself to set my clock forward one second. I suppose this proves a globe. Hahahahahaha.
For crying out loud.
Why do you think leap seconds are needed?
Supposedly to keep the Earth and seasons in synch. Add hours, lose hours. Add a second in 3 years. Whatever.
If the Earth was so in synch, there would be no need for all this crap but there's always an excuse which people buy into about all kind of utter utter shite to do with wobbles or rotations or whatever. There's too much bullshit to keep track of.
Let's put it this way. If something happens on this Earth that totally goes against it being a globe, you can bet your life that some lying bozo will make something up for why it's happened.
A little for instance:
Imagine we lost the usual run of the sun for a week and the place was frozen over and darkish. What do you think we would be told?
It would be something like, " oh the Earth has hit a strong gravitational well which has shifted it's axis for the week but all is well now."
Then they'll name it something like, a shaxis, short for shift of axis.
Yeah I'm being silly but you know what. This is the stupid game playing that we see these people do on a regular basis. They just make shit up and have people backing them up that simply accept the made up shit.
You know what. You people stick to your stupid extra second and get excited over it, because, let's face it, in time, you'll be adding lots more crap to what you think you know now, when the tefal heads start to crank up the bullshit.
