I have a project where I want to extract the timer duration (Cookbook | FIT SDK | Garmin Developers), i.e. the time where the clock has been running (not paused/stopped). However, when I use the FIT SDK Tool's .bat files, I only manage to get the "timestamp", which appears to be the time from when you start an activity, to when you end it, despite any breaks in between.
Any guidance on how to proceed would be appreciated.
