I'm trying to convert a Series in DataFrame from string to datetime, and i use the method pandas.to_datetime, it's worked! BUT it is very slow. the strings is formated as time, like '2017-1-1 00:00:00'. it's a big data, more than 3000000 data。 Are there some ways to make it work faster? appreciate your help！
