This isn't plainly written in the canon, but I think Bill was at 
Hogwarts "five years ago" on Gringotts business. Namely, Bill went to 
Hogwarts to pick up the Sorceror's (Philosopher's) Stone from 
Dumbledore and Nicholas Flamel. Bill, being a former Hogwarts Head 
Boy, was probably more trustworthy than one of the goblins. However, 
this is based on the assumption that Dumbledore anticipated Voldemort 
troubles around the time Harry leaves the care of his relatives (which 
I think he did considering the cryptic answer to Harry's question 
about why Voldemort wanted to kill him (PS/SS) and in light of 
Dumbledore's "look of triumph" in GoF.) If Dumbledore had the Stone 
put in the bank sometime during the 1990-1991 and if Bill did 
transport the Stone to Gringotts, then the last time he was at 
Hogwarts was about "five years ago".
