Two of the variables in my dataset needs to be appended into a new variable. The first of represents a data in this format (string variable): 19Nov2019, and another time in this format: 04:00. I need to create a new variable out of these two - the date and time of sessions. For example, values would be 19Nov2019 04:00; then 19Nov2019 05:00, etc. How should I do it? Thanks a lot beforehand.
