I'm looking at some of the solutions to a couple of sightseeing entries that I've found the location of on my own and the supposed time restrictions of them seem completely arbitrary and not hinted at by the clue in the log.

Example:
Log #9

"Knew it was my calling ever since I was knee-high to a goobbue. When cloudy days sunky my spirits, I'd sneak into the guild, climb as high as my legs could carry me and watch the tanners and tawers at work below." Such were the craftsman's words, and I would see as he saw.

I figured out every part, but I don't understand what in the above paragraph is supposed to tell me what the time restrictions of this venue is.

Is there something I'm missing?
