Mavproxy messages 'Time has wrapped'


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?
