Ruby 'DateTime#sec_fraction' is inconsistent across versions. #22

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

In 1.8.7, DateTime#sec_fraction is fractions of a day. In 1.9.2, sec_fraction 
is fractions of a second.

Code:
  require "date"
  p [RUBY_PLATFORM, RUBY_VERSION, DateTime.parse("2001-01-01T00:00:00.1234").sec_fraction]

Output:
["x86_64-linux", "1.9.2", (617/5000)]
["java", "1.8.7", Rational(617, 432000000)]
["x86_64-linux", "1.8.7", Rational(617, 432000000)]

1.8.6 fails completely to parse this time format.

I may need to reimplement some/all of the time parsing we do so it becomes 
reliable across ruby versions.

Behavior on 1.9.1 and 1.9.2 are similar.

["x86_64-linux", "1.9.1", (617/5000)]

Reduced priority and changed milestone.

We have decided to not support ruby 1.9.x right now because the core ruby 
library changes quite wildly between 1.8.x and 1.9.x (in both documented *and* 
undocumented ways) that it makes spending energy on 1.9.x not realistic for 1.0.

Fixed. JRuby gives us java access and we now use the Joda-Time library for date 
mangling.
