It's been a while since I've worked with MATLAB, so bear with me.
A few timing questions:
1.) What is the best way to timestamp data coming in on a serial port?
2.) What does MATLAB use to timestamp the data? Does using NTP make a difference?
Thank you for the help!

Ended up timestamping with a NIDAQ box for high accuracy. MATLAB's not "real-time" enough.

That is time in a "serial" format. Does not answer my two questions. Where is "now" being pulled from?

the now function or clock function is pulled from the system clock. If you want elapsed time between measurements without influence from the system try using the tic/toc functions with each iteration

Hi,
which NIDAQ box did you use?
best regards
