I'm not really concerned if it's the case or not, though I am the mood to ponder over Louis Arnote's warning about Elbaf. Using the Wano cover pilgrimage for comparison.
Going on the idea that Louis' warning may pertain to the flow of time being different in Elbaf then it is for the rest of the world.
I don't recall if it's stated, though I believe that Yamato's full pilgrimage on the Wano cover serial, traveling out of the Flower Capital, then to each region and back to the Flower Capital, takes place over several days. In 934, it's stated that the trip from Kuri to Udon takes "a rather long" amount of time. Traveling from one region to the next.
Kiku's explanation and Yamato's pilgrimage involving traveling to every region helps with estimates on the amount of time that would take. Relative to when the Straw Hats who are kidnapped arrive in Elbaf in 1126, which occurs two days after departing Egghead, the pilgrimage is still in Kuri. Assuming they are happening concurrently with each other.
The group traveling to Udon depart in the morning and arrive that same day though at night in 940.
So let's say it takes a day of travel to go from one region to the next for Yamato on the covers, and then a night of sleep. That's six full days or so to travel between each of the six regions. Maybe a bit more, maybe a bit less.
The kidnapped SHs arriving in Elbaf happens in 1126, and they have only been there for what they view of as a day.
Yamato is in Kuri in 1126, and has yet to travel to Udon, Hakumai, Ringo, and back to the Flower Capital. The travel time for that would be 3-4 days by my estimate. Which roughly fits the idea that Elbaf time is potentially at a 3-to-1 ratio with the outside world. If it's the case that the events of the covers are happening at the same time as the events in the main chapter.
If Yamato traveling from one region to the next always takes about a day, and assuming that he sleeps overnight in each region once before moving on to the next, the timeline is probably something like this:
The SHs see their post-Wano bounties almost right after descending the waterfall in 1058 and Luffy says his dream to the crew soon after in 1060. All of that happens on the same day. Then we get this "days later" also in 1060, which we later learn is five days after Lulucia is destroyed.
Day one of Egghead - Yamato leaves the Flower Capital before the VP broadcast begins, Tama stays.
Day two of Egghead - Yamato is in Kibi, as Tama listens to the broadcast with Kin and Momo -> Tama travels to Kuri to train.
Day after VP broadcast - Yamato meets up with Tama in Kuri.
Day the kidnapped SHs arrive in Elbaf - Yamato and Tama arrive in Udon, defeat Who's Who and co.
Day after kidnapped SHs arrive from Wano's perspective - Same day from the perspective of the SHs in Elbaf, after parting ways with Tama, Yamato travels to and arrives in Hakumai, enshrines Yasu's sword.
Two days after the kidnapped SHs arrive in Elbaf from Wano's perspective - Same day from the perspective of the SHs in Elbaf, Yamato arrives in Ringo, meets up with his bestie and learns about Moria.
Three days after the kidnapped SHs arrive in Elbaf from Wano's perspective - Yamato returns to the Flower Capital.
Maybe this isn't the case, maybe Tama returns to the Flower Capital after parting ways with Yamato and the Vegapunk broadcast happens while Yamato is in Hakumai or Ringo. Though we don't see Tama in the Flower Capital when Yamato returns. We only see her there during the broadcast throughout all of this.
If Yamato began the pilgrimage before the earthquake, which happens six days before day two of Egghead...
we may have seen it mentioned again during the pilgrimage.
The earthquake happens five days after the SHs leave Wano, before they arrive on Egghead later that day.
Unless Oda simply decided to not bring up the earthquake during Yamato's pilgrimage, it either happens after, and Yamato completed the pilgrimage in less than five days, before the earthquake happens. Or Yamato begins the pilgrimage after the earthquake, day one of Egghead, as my estimated timeline says.
