This one’s easy enough :)
So this is weird. In Ruby 1.8.7, the DateTime#sec_fraction method returned fractional seconds in units of DAYS for some reason. In 1.9.2, they changed the units – much more reasonably – to seconds.
This unbelievable little gem is taken basically straight from the YAML spec, but made slightly more readable (to my poor eyes at least) to me: yaml.org/type/timestamp.html
