Is your feature request related to a problem? Please describe.
High timing accuracy is needed for certain applications. GPS units use highly accurate timing for position measurement, and PPS (an output signal at a precise time) is supported on high end units for time synchronization. The PPS event can currently be logged as a camera feedback event, however that removes the true camera feedback ability.
Describe the solution you'd like
Allow an additional feedback pin to be logged in addition to the cam feedback
Use this PPS signal to synchronize the system clock and avoid drift
Describe alternatives you've considered
An external IMU/Logging system for photogrammetry
