Mavproxy messages 'Time has wrapped'

Hello,

I am trying to have Gremsy Gimbal control(Tilt and Yaw) using Mavlink commands. On Mavproxy console I constantly get these messages.

('Time has wrapped', 0, 4860224)
Time has wrapped
('Time has wrapped', 0, 4860684)
Time has wrapped
('Time has wrapped', 0, 4860787)

When looked at the MOUNT_ORIENTATION message, the timebootms is 0. Could this be the reason? Any suggestions?

2020-08-18 15:06:49.480;message-received;MountOrientation{timeBootMs=0, roll=0.0056271544, pitch=0.94186664, yaw=0.0, yawAbsolute=0.0}

Thanks
