Python datetime Time Processing

Time data is read in string format, converted to datetime format

data['time1'= pd.to_datetime (data['time1'],format="  %h:%m:%s:%f")

Calculate the time difference:

data['time_interval']=pd.to_datetime (data['time2')- Pd.to_datetime (data['time1')

Result: Unit or millisecond

To convert it further into seconds
