转换后的时间戳默认是UTC时间。若需要转换为东八区时间，可以使用tz_localize和tz_convert方法。首先，使用tz_localize将时间戳标记为UTC时区。然后，使用tz_convert转换为’Asia/Shanghai’时区。例如：pythontimestamp = pd.to_datetimeutc_time = timestamp.tz_localizecst_time = utc_time...

You can convert other datetime-like objects, such as Python’sdatetimeor NumPy’sdatetime64, to Timestamp objects using thepd.to_datetime()function. If you have missing or undefined datetime values represented asNaT(Not a Time) in your Timestamps, theto_pydatetime()method will handle these ...
