Here’s the code:
#!/usr/bin/env ruby
class S2hhmmss
def to_hhmmss(duration)
@duration = duration
@t = @duration / 86400 # Number of days + fraction in interval.
@DD = @t.to_i # Remove fractional part of day.
@t -= @DD # Compute fractional part of day
@hh = @t * 24 # Hours from fractional part of day.
@mm = @hh-@hh.to_i60 # Compute minutes + fraction.
@ss = @mm-@mm.to_i60 # Compute seconds + fraction.
printf ("%d days %02d:%02d:%02d\n",@DD,@hh,@mm,@ss)
end
end
dl = Time.mktime(2004,5,18,0,0,0,0.0) - Time.now
puts dl.to_s
S2hhmmss.to_hhmmss(dl)
dl /= 86400
puts dl.to_i.to_s+’ days until Teddy gets his learner’s permit!‘
puts dl.to_s+’ days until Teddy gets his learner’s permit!’
Here’s what happens when I run it:
46480555.570496
/usr/local/bin/tttdl.rb:19: undefined method `to_hhmmss’ for S2hhmmss:Class (NoMethodError)
46480541.596954
And… is there a more “Ruby-like” way to write it? (I don’t even know
whether it works…)
