huh? > can a minute ever have 59 seconds ChatGPT Yes, a minute can have 59 seconds in the context of leap seconds. Normally, a minute is defined as having 60 seconds. However, leap seconds are a way to adjust the Coordinated Universal Time (UTC) to match Earth's irregular and slowly changing rotation. When a leap second is subtracted, it technically creates a minute with 59 seconds. This subtraction has been less common than the addition of a leap second, which results in a 61-second minute, but it's theoretically possible if necessary to keep UTC aligned with solar time. The decision to insert or delete a leap second is made by the International Earth Rotation and Reference Systems Service (IERS) based on precise measurements of the Earth's rotation. As of my last update in April 2023, all adjustments have been additions, making some minutes 61 seconds long, but the system allows for the possibility of a 59-second minute if the Earth were to rotate faster than the time standards.
