ToD - Time of Day.

Like Cyberpunk 2077, The Witcher 3 also makes use of some specific Time of Day during some quest. Time gets frozen for the duration of a specific quest phase, or the clock suddently is set to another hour of the day. I find some of these to be too abrupt or not making much sense in the context of the quest, so I modified them to my liking. 

Potential spoilers

Spoiler:  Show

Main Quest - Wine is Sacred.
At the end of the quest we discover that the Cintrian will attend a party at the Mandragora that evening, and we will go there. The quest ends at 9:00 PM, so it feels like there's no time to waste, and that we need to prepare and go at the party at once (from a role play POV, because you can go there whenever you want) . Furthermore, the info related to the party was given during a scene in the ducal guard post, and we can decide to go there directly with the Dutchess. But this decision is made at 1:00 AM, more or less, so it seems like Geralt and Anna Henrietta spent an entire day there waiting for Damien.

The quest now ends at 6:00 AM.

Main Quest - The Man From Cintra

This quest has some weird time skips during the investigation. After we discover the body of the singer, the TOD goes from 11:20 PM to 3:00 AM, and once we enter the final room, it skips an hour, and goes to 4:00 AM. Quest ends at 5:00 AM.

I changed this, now it goes from 11:20 PM to 12:10 AM, and from there to 1:10 AM. Quest ends at 2:00 AM.
Players using lighting mods might benefit from this. I was using White Orchard Lighting Next Gen, and differently from vnailla Toussaint, the sun starts rising at 3:00AM, so the conversation with Oriana and Regis happened with sun light. Now it plays during the darkness of night, preserving the intended mood.

Side Quest - Big Game Hunter

This quest also has weird time skips. It locks time passing once you open the map, then after the scene with the centipedes it skips time to 1:27 PM, and after the next phase you go back to camp, and time skips at 7:00 PM. This is too abrupt, so I changed it to 12:00 PM for the first skip, and the return to camp is at 13:00PM
