   I've shared the code above:
   set hive.local.time.zone=Europe/London;
   
       HIVE_LOCAL_TIME_ZONE("hive.local.time.zone", "LOCAL",
           "Sets the time-zone for displaying and interpreting time stamps. If this property value is set to\n" +
           "LOCAL, it is not specified, or it is not a correct time-zone, the system default time-zone will be\n " +
           "used instead. Time-zone IDs can be specified as region-based zone IDs (based on IANA time-zone data),\n" +
           "abbreviated zone IDs, or offset IDs."),
   
   ````
   public ZoneId getLocalTimeZone() {
     String timeZoneStr = getVar(ConfVars.HIVE_LOCAL_TIME_ZONE);
     return TimestampTZUtil.parseTimeZone(timeZoneStr);
   }
   SessionState.get().getConf().getLocalTimeZone()
   ````
