In this case I don't think we know the position of the timestamp
so a structure would be misleading.

The comment above the define certainly suggests it is variable..

/*
 * Maximum of 6 + 6 + 2 + 7 (for MPU9x50) = 21 round up to 24 and plus 8.
 * May be less if fewer channels are enabled, as long as the timestamp
 * remains 8 byte aligned
 */
#define INV_MPU6050_OUTPUT_DATA_SIZE         32
