"Hawaii Time" refers to the standard time zone used in the Hawaiian Islands, which is 10 hours behind Coordinated Universal Time (UTC-10). While "Hawaii Time" is the official and commonly used term, there are a few other synonyms for it. For example, it can also be referred to as "Hawaiian Standard Time" or "Hawaiian Time Zone".
