   time=times.split("/").join("-")
end

Aside 1: it's unconventional to put an exclamation mark at the end of a
method name, if the method does absolutely nothing dangerous, nor does
it modify the receiver.

Aside 2: no need to assign the result. Also, 'times' is not known.

Here's a corrected version:

def convert(time)
  time.split("/").join("-")
end

Here's an alternative one:

def convert(time)
  time.gsub(%r{/}, '-')
end
