If you are sorting a table by date/time then it might possibly make more sense to use a timetable than a plain table, depending on the processing you are doing.
When you convert the resulting timetable to plain table, and then table2struct, the order would be sorted by the time key.
If for some reason you need to get back the original order, then before sorting add a column that is the row index; then you could sort by that to get your original order.
