Return `true` if the specified `timeValue` is a non‐negative integer that represents a valid nine‐digit time value suitable for passing to `convertFromHHMMSSmmm`, and `false` otherwise. `timeValue` is a valid nine‐digit time value if, when expressed in decimal notation, it contains exactly nine digits (counting leading zeros, if any): two digits for the hour, two digits for the minute, two digits for the second, and three digits for the millisecond, where either `0 <= hour < 24`, `0 <= minute < 60`, `0 <= second < 60`, and `0 <= millisecond < 1000`, or `240000000 == timeValue`.
