Really? You have difficulty understanding that time passes as the story unfolds?
Are you sure that you're old enough to be visiting this page, playing this game, or commenting online?
There is nothing worse than:
MC: I think I will go outside
BLACK SCREEN: A few minutes later
MC: I'm now outside
To begin with, those transitions are extra work for the dev, and unnecessary for anybody with the slightest understanding of the concept of time.
The only exception would be if the characters are in the same location, wearing the same clothes, standing in the same pose, but from one text box to the VERY next moves time forward by more than 30 minutes.
And if that is the case, I would suggest that the game would be unplayable for more reasons than that.
