   > Actually, this is already possible via the `TIME_GRAIN_ADDONS` and `TIME_GRAIN_ADDON_EXPRESSIONS` variables [in `config.py`](https://github.com/apache/superset/blob/master/superset/config.py#L542-L565), thanks to @villebro!
   
   When i using that but not working.
   This my code in config.py:
   TIME_GRAIN_ADDONS = {
       'PT2S': '2 second',
       "PT6H": "6 hours",
       "PT15M": "15 minutes",
   }
   
   TIME_GRAIN_ADDON_EXPRESSIONS = {
       'postgresql': {
           'PT2S': 'toDateTime(intDiv(toUInt32(toDateTime({col})), 2)*2)',
           'PT6H': "date_trunc('day', {col}) + date_trunc('hour', {col})::int / 6 * interval '6 h'",
           'PT15M': "date_trunc('hour', {col}) + date_part('minute', {col})::int / 15 * interval '15 min'",
       }
   }
   
   What am I wrong?
