total hour of yt360 dataset

[sivannavis]

Hi! Thanks for the great work. I downloaded the yt360 dataset based on your train/test split files, and calculated the total length of those videos, it seems the total hour is around 667.8 hrs, which is inconsistent with the 246hrs on the dataset website. I'm wondering if there's any change in the dataset or do you curated the clips in specific ways? Thanks!
