In 'C++', you could just pass (int) ch which should return the numeraical ascii value. .
Printf("%d\n", c);

Http://rails.rubyonrails.org/classes/ActiveSupport/CoreExtensions/Time/Calculations.html#M001139 documents a method advance() to add to the current time. Is there an opposite, ' go_back() method?
Answer Snippets (Read the full thread at stackoverflow):
Time.now.advance(:days => - 1, :hours => -1)
You can use something like
Time.now - 3.days
for example
You could also try using
Time.now.ago(3.days) Time.... .
I don't think there is but there's nothing to stop you using negative values in advance .

In Perl, localtime takes a Unix timestamp and gives back year/month/day/hour/min/sec etc. I'm looking for the opposite of localtime : I have the parts, and I'd like to build a unix timestamp from them.
