Description

Time.strptime does not appear to be handling Julian dates, it is defaulting the date to be whatever is provided as "now" (e.g. January 1). I believe this is because Time is calling Date._strptime which returns a hash with {:yday=> ...} and does not handle the yday keyword.

Found in 2.3.3, verified not working in 2.5.1.

require "time"
require "date"

### Works for Dates ###
parsed_date = Date.strptime("15300", "%y%j")
expected_date = Date.new(2015, 10, 27)
# Does not raise
raise "dates not equal" if expected_date != parsed_date


### Does not work for Time ###
parsed_time = Time.strptime("15300", "%y%j")
expected_time = Time.new(2015, 10, 27)
# Raises
raise "times not equal" if expected_time != parsed_time
