Isaacsim2022.1.1 imu_readings timestamp error

the timestamp get from the Isaac Sensor Extension [omni.isaac.isaac_sensor] — isaac_sim 2022.1.1-release.1 documentation imu sensor api will reset when simulation stop then start, i think it is a bug in isaacsim2022.1.1

When stop is pressed, the simulation/physics are reset and the timestamps returned will be reset as well.
