stardis: comment on time conversion
The conversion of a duration in seconds to day_1850 does not take leap
seconds into account. This approximation is justified by the simplicity
of the conversion, given the marginal approximation it introduces.
As an additional argument, the day_1850 data itself is certainly
calculated without taking this detail into account.
