YouTube url in specific video time

Hello, daer costaszissis.

Thank you for contacting us!

Yes, we have such an opportunity in the gallery. Please, when you add a link from YouTube after the link, add this symbol “& t = 10”. 10 number can be changed. This means from what second do you want the video starts.

Have a good day!

Sincerely, Total-Soft

Thank you, but I am so sorry to say it is not working in my case:

The second video ulr is https://youtu.be/Z2Op6i1uWc8?t=13 and this is automatically changed to https://www.youtube.com/embed/Z2Op6i1uWc8?start=13s as inserted for some reason.
Any idea please?

Sincerely,

Costas
