There's a neat trick to make this possible. Just add to the end of the URL ?t=time in seconds
For example, this is the link for the video I want to share in the forum:
Now, if I want a specific time in the video, where the goal happened at 3:26 (3 minutes and 26 seconds), I use the same link, but add ?t= plus the time in seconds to the end:
3 minutes = 180 seconds (3×60 seconds)
+ 26 seconds
= 206 seconds (180 + 26 seconds)
Adding that to ?t=206 and to the end of the video links to that specific time.
I hope this helps :)
