如何将UTC时间戳字符串转换为pandas datetime？

Question

I have a panda dataframe with a column with date format as below:

PublishDateTime= 2018-08-31 12:00:00-UTC

I used panda to_gbq() function to dump data into a bigquery table. Before dumping data, I make sure that the format of columns match with table scheme. publishedate is timestamp in bigquery table. How can achieve something similar to:

df['PublishDateTime'] = df['PublishDateTime'].astype('?????')

I tried datetime[ns] but that didn't work!

Answer 1

The main challenge in the conversion here is the format of your datetime. Pass format="%Y-%m-%d %H:%M:%S-%Z" as an argument to pd.to_datetime and convert your column to datetime .

df['PublishDateTime'] = pd.to_datetime(df['PublishDateTime'], 
                                       format='%Y-%m-%d %H:%M:%S-%Z', 
                                       errors='coerce')
