The earth is rotating slightly slower than it used to. We occasionally have to add an extra leap second onto the last day in december How many seconds are there in december when a leap second has been added? PLEASE ANSWER THIS IF YOU KNOW IT OT WILL HELP ME SO MUCH THX

answer:A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between precise time (as measured by atomic clocks) and imprecise observed solar time (known as UT1 and which varies due to irregularities and long-term slowdown in the Earth's rotation). The UTC time standard, which is widely used for international timekeeping and as the reference for civil time in most countries, uses precise "atomic time" and consequently would run ahead of observed solar time unless it is reset to UT1 as needed. The leap second facility exists to provide this adjustment.

a negative exponent is translated as follows:

so, we have
