Transit and timing

Sub-Lord Changes

get_sublord_changes

Hours until each planet's KP sub-lord changes next, however far off that is (a slow planet's next change can be months away). Sub-lord boundaries are when transit influence shifts. A sign line inside a sub is not a change, because the star and sub lords run across it; it is listed in 'signChangesOnTheWay'. Returns '{ fromDatetime, changes: [{ planet, currentKP, currentStarLord, currentSubLord, nextChangeUTC, nextKP, nextStarLord, nextSubLord, hoursUntilChange, signChangesOnTheWay[], searchCapReached }] }'; 'hoursUntilChange' is -1 only when 'searchCapReached' (three years with no change). For all sub-lord crossings within a date window (with minute-precision binary search) use 'get_transit_crossings'.
