I am trying to correct HIGHRES_IMU data with Unix time of each message by comparing to SYSTEM_TIME' message that provides both Unix and time since system boot. However, as a result shown in my record, the
SYSTEM_TIME` gave me some wried value as follow:
pixhawk_time_unix_usec pixhawk_time_boot_ms current_unix_time

the problem is on this line
7.99867651800583E+018 704532493 1513510376314139
I recorded the data for 4 hrs, and this problem shows only one time
how it came and is it another information sending via SYSTEM_TIME
message?
