Fix the problem that the Sensor Frameowk and UAF use different data
format

- Problem: The data format of timestamp is not different from the sensor framework.
- Cause: The UAF uses 32 bit timestamp but the sensor framework uses 64
bit timestamp.
- Solution: Change timestamps in UAF with 64-bit unsigned long long.
