 *
 * @remarks The Javascript `Date` type most closely resembles a Fauna `Time`,
 * not a Fauna `Date`. However, Fauna stores `Time` values with nanosecond
 * precision, while Javascript `Date` values only have millisecond precision.
 * This TimeStub class preserves precision by storing the original string value
 * and should be used whenever possible to pass `Time` values back to Fauna.
 * Converting to a Javascript date before sending to Fauna could result in loss
 * of precision.

 * Javascript `Date`, we set time to 00:00:00 UTC. When converting a Javascript
