No, really, a time course consists of different time points, not points in time. I have been measuring at different time points for ten years, five of which in the UK. So have my colleagues. It is a common expression in science, which is what this text is about.
An example (copy and paste from a scientific abstract from Edinburgh, found online):
"Concern that HIV infection may result in the premature development of end stage liver disease has led us to investigate hepatitis C viral loads in haemophiliacs at different time points before and after HIV infection."
