/**
 * UUID like common format
 *
 * Old UUID format:
 *
 * [timeLow]-[timeMid]-[custom1]-[custom2](part1/2)
 *  -[custom2](part2/2)[random1][random2]
 *
 * timeLow: 8 chars, seconds in microtime, hex format.
 * timeMid: 4 chars, micro-second in microtime, plus 10000, hex format.
 * custom1: 4 chars, user defined, '0000' if empty, hex format suggested.
 * custom2: 8 chars, user defined, hex of user ip if empty,
 *          and random hex string if user ip cannot get, hex format too.
 * random1: 4 chars, random string, hex format.
 * random2: 4 chars, random string, hex format.
 *
 * New UUID format move custom2(part2) to random part, parts are splitted
 * separator.
