While we're at it, can we please get rid of leap seconds? (which we don't know are going to happen until ~six months beforehand?) Just wait until we are off by a full minute, and then we'd know at least a full decade ahead of time when the next leap minute will happen. I don't understand the need to have it so precisely align with astronomical measurements (to the nearest 0.9 seconds) when we already do so much roundoff due to time zones, daylight time, etc.
