Find the closest date in an array of dates

gistfile1.rb

# I have an array of dates (both past and present) and a single date ('needle' below),
# for which I want to find the closest date in either direction. Here's my solution; 
# can you think of a better one?

dates.sort_by { |date| (date.to_time - needle.to_time).abs }.first

agree that my comment might not be on point after all, thanks for pointing that out @chiperific

funnily enough in this particular data set the min does work without the abs()

dates
