Do both imply the same meaning?
- John told me to be there at 6pm. I will be there on time.
- John told me to be there at 6pm. I will be there in time.
- John told me to be there at 6pm. I will be there at that time.
I can feel that in time needs a for or a to but am not sure. Like in I'll be there in time for the show to start. or I'll be there in time to see it. (on time won't work)
