    Heya,

    I just found out something that's causing me issues with my TF's in ROS2. Shouldn't the timestamp of the ROS2 msgs be constructed from both nanosecs and secs?

    In the camera_interface.cpp only the nanosecs field is populated causing the timestamp to be incompatible with any ROS2 time conventions.

    This however is not the case in the imu_interface.cpp which works as intended.

    Thought I would point it out!

        @smilon , we have a merge request that is being tested - https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-to-ros2/-/merge_requests/8/diffs?commit_id=a128608d0ad1e4c417edc7013f9bbbf9665b754b#diff-content-bbec15f81097cb24d4e021ae03a1c7aa01ff13d6

        Can you please take a look and help confirm this is what you are expecting?

        Thank you 🙂

          @smilon You can find an updated package here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mpa-to-ros2_0.0.2-202402291159_arm64.deb. This should work fine with SDK 1.1.2.
