Candidate Notes:

Run the tests using the command: rails test

Basically, the default options of 10 to 19 hours and PST8PDT timezone were kept, while providing a way to customize work hours for each day of the week and to provide a another time zone.

An example to customize weekend available hours below:

schedule = StaffMemberSchedule.new(
  since: Time.new(2018, 7, 27),
  till: Time.new(2018, 7, 30),
  staff_member: StaffMember.new(
    schedule: {
      sun: ['14:00', '16:15'],
      sat: ['14:00', '16:15']
    }),
  duration: 45.minutes
)
schedule.openings

Any weekday can be customized sun mon tue wed thu fri sat.

To customize the timezone, simply add the timezone argument to StaffMember.new as below:

utc = Time.find_zone("UTC")

schedule = StaffMemberSchedule.new(
  since: Time.new(2018, 7, 27),
  till: Time.new(2018, 7, 30),
  staff_member: StaffMember.new(
  	 timezone: utc,
    schedule: {
      sun: ['14:00', '16:15'],
      sat: ['14:00', '16:15']
    }),
  duration: 45.minutes
)
schedule.openings

Also, some unused variables and methods were deleted to not create interference with this candidate's understanding.
