i see the issue too. And maybe i found the reason: When create a chart with time grains, superset will use it's default db_engine grains(mysql, db2, clickhouse...), like clickhouse: [https://github.com/apache/superset/blob/master/superset/db_engine_specs/clickhouse.py](https://github.com/apache/superset/blob/master/superset/db_engine_specs/clickhouse.py) code: > class ClickHouseEngineSpec(BaseEngineSpec): # pylint: disable=abstract-method > """Dialect for ClickHouse analytical DB.""" > > engine = "clickhouse" > engine_name = "ClickHouse" > > time_secondary_columns = True > time_groupby_inline = True > > _time_grain_expressions = { > None: "{col}", > "PT1M": "toStartOfMinute(toDateTime({col}))", > "PT5M": "toDateTime(intDiv(toUInt32(toDateTime({col})), 300)*300)", > "PT10M": "toDateTime(intDiv(toUInt32(toDateTime({col})), 600)*600)", > "PT15M": "toDateTime(intDiv(toUInt32(toDateTime({col})), 900)*900)", > "PT0.5H": "toDateTime(intDiv(toUInt32(toDateTime({col})), 1800)*1800)", > "PT1H": "toStartOfHour(toDateTime({col}))", > "P1D": "toStartOfDay(toDateTime({col}))", > "P1W": "toMonday(toDateTime({col}))", > "P1M": "toStartOfMonth(toDateTime({col}))", > "P0.25Y": "toStartOfQuarter(toDateTime({col}))", > "P1Y": "toStartOfYear(toDateTime({col}))", > } to fix this issue , you can change the code to support your local time zone. or if you just need dt grains, you can just let zhe chart's time grains to null. -- This is an automated message from the Apache Git Service.
