In many applications, 32-bit resolution is required to measure external signals with long periods (up to several hundreds of seconds), or to generate delays or periodic signals with similar periods.

This page states that it uses std::clock() to get the time, which has 1ms resolution, which I would like better than, if possible. This old page: http://unitedsoft.ch ...

Oscilloscopes utilize both hardware and software tools to enhance the resolution of time measurements. Happily, most of the processing is transparent. The primary display from an oscilloscope is ...
