It is not Windy bug.
That is how Leaflet map handles antimeridian.
Workaround is to split polyline at -179.9 & +179.9 deg.
For best visualt result make 3 polylines.
One between longitudes -179.9 ... + 179.9
"Ghost 1" -270 ... -180.1
"Ghost 2" +180.1 ... + 270
I guess it is same bug:

Ivo said it is fixed and is waiting for deployment.
Incorrect zulu:
Using mouse to change bottom timeline.
Sometimes it 3h diff, sometimes it is far off as 17h when moving end of timeline. (Using arrow keys next makes UTC correct)
Correct zulu:
Using keyboard arrow keys to move bottom timeline.
Meteograms show correct zulu.
No problem with that.
Even I had forgotten that it is possible to rename favourites.
So I renamed my favourites also after your question :)
@bstavrev
It is possible to rename your favourites.
Just double click on that name and then you can rename it.
Maybe it is better to add link to this red screen?
"Use embed Windy widget" or something like that to link

Windy is not climate tool.
Climate & weather are very different things.
The problem is in: https://api4.windy.com page?
Or in your own page?
Make sure you use your own API key in your application.
