Genshin Impact Time and Wind quest guide – unlock the two secret sundials

gamepur.com:

Genshin Impact has a massive amount of side-quests and hidden achievements. One of these quests, Time and Wind, requires you to travel to a small island not charted on your map and do some detective work to unlock the two secret sundials. This quest can be done at any time, but we recommend bringing some stat food and a few non-Anemo characters with decent gear before you begin. Here’s the Time and Wind quest guide to discover the secret of the uninhabited island.

Note: While you want non-Anemo characters for the boss fight, make sure Traveler is attuned to Anemo before beginning the trip (or bring an Anemo character with a fast-recharging Elemental Skill.) There are puzzles that require Anemo skills to solve.

There are two ways to reach the island — by having at least 200 stamina and stamina-replenishing food and jumping from Starsnatch Cliff (pictured below,) or by using Kaeya’s Elemental Skill and building an ice bridge from the coastline to the island. The former is definitely faster, but it requires you to have obtained many Anemoculi and Geoculi and leveled your Statues of the Seven up a fair amount. If you’re not quite at that point, then the ice bridge method will work — but it will take around 20 minutes, and if you fail to spam the ability you can get reset back to the shore.

When you arrive at the island, head to the center and find the Ravaged Carving. This is the first of the sundials, and by interacting with it Paimon will mention using Elemental Sight (middle mouse button on PC or L1 + Left D-Pad on controller.)

Head to the beach on the right side of the carving and you will find a pile of rocks near a tent. Smash them to find the note that you need.

Head back to the Sundial and change the time of day to
