The code I quoted was designed to be independent of sample loss. Since it is determining the time between samples and use it as the interval for each integration, if you lose a sample, it will integrate with double the interval the next time. So it won't throw you off. I wouldn't assume a fixed sampling rate. I would figure out if the system has a hardware timer that you can read that will give you an accurate timestamp.
