def adjust_end_datetime(field, start_timestamp, new_datetime)
  # If setting 'end' time and the parsed new_datetime (based on start_date)
  # is earlier than or same as start_time, assume it's for the next calendar day.
  if field == 'end' && start_timestamp && (new_datetime.to_i <= start_timestamp)
    new_datetime += (24 * 60 * 60) # Add one day
  end
  new_datetime
end

#create_new_datetime(_base_date_time, parsed_time_component) ⇒ Time

Creates a new datetime object based on the parsed time component.

Parameters:

  • _base_date_time (Time) —

    The base date and time (not used for date components).

  • parsed_time_component (Time) —

    The parsed time component.

Returns:

  • (Time) —

    The new datetime object.

def create_new_datetime(_base_date_time, parsed_time_component)
  Time.new(
    parsed_time_component.year,
    parsed_time_component.month,
    parsed_time_component.day,
    parsed_time_component.hour,
    parsed_time_component.min,
    parsed_time_component.sec,
    parsed_time_component.utc_offset # Preserve timezone context
  )
end

#determine_base_date_time(_item, field, start_timestamp) ⇒ Time

Determines the base date and time for creating a new datetime object.

Parameters:

  • item (Array) —

    The item being modified.

  • field (String) —

    The field being validated (‘start’ or ‘end’).

  • start_timestamp (Integer, nil) —

    The start timestamp of the item.

Returns:

  • (Time) —

    The base date and time.

Raises:

  • (ArgumentError) —

    If the field is ‘end’ and the start timestamp is not set or if the field is invalid.

    The new end time in epoch format.

  • start_timestamp (Integer) —

    The start timestamp of the item.

  • new_datetime (Time) —
