There is no paradox in the scenario described in post #1.

When person S returns to near and rest relative to person E, clock E reads 1 year:0 days:12:05, and clock S reads 1:0:12:00. Both agree that the Sun has aged 1:0:12:00 as measured by clock E. That this age disagrees with clock S is no more paradoxical that clock S disagreeing with clock E.

The reader may find it helpful to visualize that, compared to the speed of person S relative to person E (about .004357 c, accounting for both special and general relativistic time dilation, and assuming that person S doesn’t experience a prolonged high acceleration), the speed of person E relative to the Sun (about .00009935 c) is practically zero. The sun and person E can practically be considered the same inertial frame.
