Convert to/from DateTime and Time in Ruby

Question

How do you convert between a DateTime and a Time object in Ruby?

Answer 1

Improving on Gordon Wilson solution, here is my try:

def to_time
  #Convert a fraction of a day to a number of microseconds
  usec = (sec_fraction * 60 * 60 * 24 * (10**6)).to_i
  t = Time.gm(year, month, day, hour, min, sec, usec)
  t - offset.abs.div(SECONDS_IN_DAY)
end

You'll get the same time in UTC, loosing the timezone (unfortunately)

Also, if you have ruby 1.9, just try the to_time method
