In DateTime.jd, some Rational numbers cause RangeError (bignum too big to convert into `long') #5791
Description
I am getting this error in my rspec runs in the logstash-input-jdbc.
The Sequel gem (5.22.0) is using tzinfo (2.0.0) to generate DateTime instances when a timezone conversion is being done between the database timezone and the LS application timezone. In some cases a rational number that has very large numerator/denominator combinations is supplied to the jd class method on the JRuby DateTime class. This breaks with a RangeError (bignum too big to convert into `long'). It is easy to reproduce in IRB.
