 * TimestampFirstCombCodec encodes and decodes COMBs, with the timestamp as the

 * In contrast with the TimestampLastCombCodec, the TimestampFirstCombCodec

 * timestamp-first COMB, set the TimestampFirstCombCodec as the codec, along
 * with the CombGenerator as the random generator.

 * ``` php
 * $factory = new UuidFactory();
 *

 *
 * $factory->setRandomGenerator(new CombGenerator(
 *     $factory->getRandomGenerator(),

 * ));
