second

Returns the second within a serial Julian date and time value. Care must be taken in handling rounding errors appropriately, because time is expressed as a fraction of a 24hr day. Therefore 1sec is ~0.000015 days. Given this fraction, this function first calculates the number of seconds that have lapsed into the current day, rounding to the nearest second. The seconds that make up a whole number of minutes are then subtracted with the remainder being the number of seconds in the current minute.
