It would be true if today was January 1st and he turned 18 the day before, on December 31st.
For example, say it was January 1st, 2007. Then on December 31st, 2006 he turned 18. Thus he was 17 up through "the day before yesterday" (Dec 30). At the very end of this year he has another birthday and turns 19. Then in 2008, at the very end of the year, he turns 20.
Notice that it's not necessary that he was born on midnight on any particular day. That wouldn't factor in anyway, as midnight is always the next day. And having a birthday on February 29th doesn't make sense either, because if you count the birthday as the only day when he turns a higher age, then it would take 4*(20-17)=12 years to get from 17 to 20. If his birthday was on February 29th and you celebrated it on March 1st on non-leap years anyway, it still couldn't answer the question.

Andrew was born on Feb. 29. Because his birthday only happens once every 4 years.
