Alright, she repeated many times "Log date 7112" the same day when making logs on Too far, and that counts as a day since she said it early in the morning, in the Kindergarten and at evening. Since 7112 days are around 23 years (that's not a precise number), the thing is there's a big plot mistake (if we notice the log date of Warp Tour).

Now, since you said Peridot's not wrong, that only means there's a difference between homeworld days and earth days.
