"Slip" makes it sound like a retrospective change in the relationship between UTC and time_t, with the scales sliding against each other, but it doesn't change - there's a fixed relationship between UTC second labels and time_t second labels, which remains the same however many leap seconds there are. In fact time_t is defined in terms of that relationship, and "seconds since the epoch" is just a simplified gloss.
