Definition

<Relative Time>, <Absolute Time Interval>, and <Relative Time Interval> instances may each have a component <Absolute Time> instance, and the restrictions on their field values depend on the value of the <Absolute Time> component, when it is present.

1. If an <Absolute Time> is present with a time_value.time_configuration entry specifying that the day field value is not applicable,
   1. for <Absolute Time Interval> and <Relative Time>, delta_days = 0.
   2. for <Relative Time Interval>, delta_start_days = delta_stop_days = 0.
2. For <Absolute Time Interval> and <Relative Time>, if an <Absolute Time> is specified for which month is not applicable but day is applicable, delta_days shall be in the range (1 - day) to (30 - day) where day is the <Absolute Time>'s day field.
3. For <Absolute Time Interval> and <Relative Time>, if month and year are not applicable, then day shall be in the range [0, 365] inclusive.
4. If no <Absolute Time> component is present, or restrictions 1-3 do not apply, then delta_days has no constraints for <<Time Dependency>>.

Rationale

1. No meaningful delta values can be applied to the day value of an <Absolute Time> for the case where a day value is not specified by that <Absolute Time>'s SE_Time_Configuration.

2. A <Time Interval> that is referenced to an <Absolute Time> for which no specific month is specified is assumed to have a 30 day month, and the interval cannot exceed a 30 day period.

3. When using day of year (rather than explicitly specifying the month) for an unspecified year, the year is assumed to be a 365-day year.

4. Part 4 of this constraint only applies to the cases explicitly specified by the constraint.

5. If the day of the year is specified rather than a specific month, then the day shall fall within the bounds of a 365-day year (negative days in a year are not defined).
