The TimeNum companion object is used to represent and operate on date-time values. It contains an implicit class definition for TimeNum, which extends Instant with Numeric operations that can be used in VectorT. The java.time.Instant class stores nano-seconds since the UNIX Epoch using a long for seconds and int for nano-seconds (12 bytes or 96 bits). The java.time.ZonedDateTime class is used with it to handle various date-time formats.
