Found and fixed an issue that occurred on 32-bit linux. When using 5 minutes for a quality timestep, the timestep computed was 299 seconds, not 300. I traced it to an apparent truncation issue in the hour() function in input3.c. The time string is converted into a double value representing the timestep which is then later converted into seconds and cast to a long. it appears that during the cast, the value is truncated to 299, not 300.
