Reset time of SparkFun OpenLog Artemis

Development Boards Artemis
1

I am using 20 Openlog Artemis to record the IMU and Gyros data. I need to compare these values with each other so I need very accurate timestamps.

Does anyone knows the reset time of the IMUs when the are already powered on. I am not talking about a cold restart.

Also, how do I adjust the reset time so that all the IMUs can start recording at the exact same time.

Thank you in advance.
