[R] Adding minutes to 24 hour time

Does anyone know how to add minutes (up to 100 min) to a 24 hour time, to create a new 24 hour time? I can't seem to find any documentation or examples explaining how to do this. The variables of interest are 'ARRIVE','WAIT', and 'DEPART' in the attached partial dataframe. I want 'DEPART' to be the "sum" of 'ARRIVE' and 'WAIT' in 24 hour format. Also, can anyone direct me to some relevant documentation?

Thank you,
