If you want more excat value, U can change it for youself. # Fix the Min Interval check bugs, move the check before write the current data to data hist file. # Add the Max Interval var, default value is 1800, if the hist data file is too old, drop the result. # Fix the for output "Maybe 32 bit counter overflow, because we got a negative value here." when check too frequent.
