> The default TimeRange constructor creates a range from 0 to Long.MAX_VALUE and sets an
allTime flag to true. This flag allows some performance optimizations when comparing or using
TimeRanges.
> This flag is not set, however, if you call "new TimeRange(0L)" or "new TimeRange(0L,
Long.MAX_VALUE)", even though both of these create a logically equivalent TimeRange to "new
TimeRange()". Since TimeRanges are immutable and detecting this condition is trivial, we should
set the flag automatically in the explicit constructors when appropriate.
