1 янв 3023 г. - Due to the lunar tides decelerating the Earth's
rotation, the average length of a solar day will
be 1⁄30 SI second longer than it is today. To
compensate, either a leap second will have to
be added to the end of a day multiple times
during each month, or one or more
consecutive leap seconds will have to be added
at the end of some or all months.
