Dimmsdale in the year 1992 was shown in the third season episode The Secret Origin of Denzel Crocker. The city was not very different from present day Dimmsdale however the citizens were in there 30's  and sported styles from the early 1990's. This was, also, the year Timmy Turner's parents purchased their present home in Dimmsdale presumably after Chet Ubetcha ran them to the other side of town according to the episode Poltergeeks. Denzel Crocker also began teaching at Dimmsdale Elementary School in this year. Timmy's mom was shown to be pregnant with him. They were hoping for a girl, which explains the pink hat abd Timmy wearing dresses.
