can't convert Fixnum into String in relativity

good day i read about relativity gem but when i try to use it and make
a test file and build it gives me an error

=test.rb=
<pre>

require 'relativity'
opens_at = DayTime.new(9) #=> 09:00:00
closes_at = DayTime.new(12,30) #=> 12:30:00
</pre>

<pre>
/home/start/.rvm/gems/ruby-1.9.2-p290/gems/relativity-0.0.8/lib/
relativity/day_time/new.rb:24:in `BigDecimal': can't convert Fixnum
into String (TypeError)
  from /home/start/.rvm/gems/ruby-1.9.2-p290/gems/relativity-0.0.8/lib/
relativity/day_time/new.rb:24:in `initialize'
  from /home/start/Aptana Studio 3 Workspace/jquery/javascript/test.rb:
2:in `new'
  from /home/start/Aptana Studio 3 Workspace/jquery/javascript/test.rb:
2:in `<main>'
</pre>

Thanks for the feedback.

For ruby 1.9.2 this was indeed a bug in version 0.0.8.
(because BigDecimal.new() did not take Integer argument).

I resolved that in version 0.0.9, so could you check please which
version of relativity you are using.

To update to a new version, in a gemset that I had not updated yet,
I could successfully run this (did that just now):

$ gem list | grep relativity
relativity (0.0.8, 0.0.7, 0.0.6, 0.0.3)
$ gem install relativity
Fetching: relativity-0.0.9.gem (100%)
Successfully installed relativity-0.0.9
1 gem installed
$ irb
1.9.2p290 :001 > require 'relativity'
=> true
1.9.2p290 :002 > DayTime.new
=> 13:56:55

Note: it will not work at al in ruby 1.8.x because I am
using some newer Regexp features.

Thanks,

Peter
