When are the floor resets and are they at the same time on every world?

Question

When are there floor resets and are the resets the same time on every world?

Answer 1

• Floor reset happens in different places at different times.
• The time a floor reset happens will be always the same for a given place (example: If you notice a floor reset in a tomb at 9pm you can be sure that each day if no players are around, there will be a floor reset at 9pm in that tomb).
• Floor reset happens 4 times per day with periods of 6 hours between each floor reset.
• A floor reset will occur in a method similar to creature respawns. When no players are near an area that's going to have a floor reset the place will be reset, but if someone was or is near that area it will be no floor reset.
• Locations that receive more player-traffic will not have many floor resets. For example, floor rarely resets in towns where there are almost always people walking around.
• Some places never reset (only on game updates). Such examples are scarab caves and dwarf mines.
• After a Server Save there will be always a floor reset (unless is a place that only resets after an update).
• After a floor reset Daily Respawns of items will occur.
• The Feyrist peninsula has an unusual frequent rate of one floor reset every 30 minutes because of its changes during the day/night cycle.
  
  Pretty sure they're the same on every world (based on their server time) outside of these rules.

Answer 2

 

I just wanted to add that because a lot of players were complaining about FPS rates and the litter in hunting grounds (like glooth bandits) they now announced it will be a daily occurrence every server save. However, some spawns are still needing to be fixed to have a reset as well. This news is dated September 16, 2019:

Map Refresh

n order to combat littering in hunting grounds, we have introduced a new refresh mechanism.

Tomorrow's server save will result in a map refresh which affects all areas except cities and houses. Any items which are left on the ground will be removed. This will from then on be a daily occurrence. Cities where refresh mechanisms have existed previously will continue to function as before.

Before September 21^st 2011 there were few different times of for the server saves. On this date Cip synchronised the daily server saves to improve maintenance processes. From then on, the daily server save takes place at 10:00 CEST/CET on all game worlds.
