After clockwork allowed Danny to use his time portals, he started to have fun with them.
Danny was playing with time, or better yet, just making the time line how it was supposed to be.
Like
Danny is in the past and meets Hippolyta and the Amazon while in a battle against Hercules and the monsters of Hades.
Hades was on vacation; let Hercules take care of the Underworld. (Never TRUST A CHILD OF Zeus. ONLY WHEN SHE IS YOUR wife.)
Or the times he fought against Blackbeard (Vandal Savage) or helped Genghis Khan as a Ghost tried to kill him. (Again Vandal Savage)
He trained under an old man after he was saved from a cage in the desert for many years too, with his dead wife inside of it with him.
Or the time he worked with Martian Manhunter, Dr. Fate, and a few others against an invasion by Darkseid in the past.
So back in the present, Danny notices the painting he saw a few days ago and thinks it's similar to him: It Was Actually Him The Whole Time.
Danny had not changed to a different time line; it was the original time line.
Clockwork explained it to him: Danny changed the past; it was the whole time. He is outside of it, but not fully; it happened after his fight with Dan.

Well, someone should have told Dani about the kind of Chaos her Genetic donor had caused in the past. So she wouldn't be on such a run from so many people! After they only met her once!
Many people Danny has met in the past are very interested as they saw and meet Dani.

Short.
Clockwork pulls absolutely favor Danny and Dani over the rest of beings. So they are part of time, like him.
Something like that Vlad would never get away with, and other ghosts would have been just erased or, worse, hunted down by time hunters.
Like a Hound of Tindalos.
I like them; they are cute.
