timedelta初始化参数包括天 days、秒 seconds、微秒 microseconds、毫秒 milliseconds、分钟 minutes、小时 hours、星期 weeks,但内部实际仅存储天、秒和微秒,其它单位会被转换。 代码: >>> from datetime import timedelta >>> delta = timedelta(weeks=1, days=2, hours=3, minutes=4, seconds=5, microseconds=...
Without timezone, with microseconds:from datetime import datetime print (datetime.now().isoformat()) Output:2019-11-01T10:42:00.720818 With timezone, with microseconds:from datetime import datetime from dateutil.tz import tzlocal print (datetime.now(tzlocal()).isoformat()) ...

Internally, the ClickHouse server always stores any DateTime or DateTime64 object as a time zone naive number representing seconds since the epoch, 1970-01-01 00:00:00 UTC time. For DateTime64 values, the representation can be milliseconds, microseconds, or nanoseconds since the epoch, depending...
The default behaviour is to try and detect the correct precision, but if this is not desired then pass one of ‘s’, ‘ms’, ‘us’ or ‘ns’ to force parsing only seconds, milliseconds, microseconds or nanoseconds respectively. lines : boolean, default False Read the file as a json ...
