Defined checkUpdating() interface

        void clearOffset() raises (ComponentErrors::ComponentErrorsEx);

        /** Check if the updating is feasible at the required starting time.

         *

         *

         * @param starting_time the UTC time the scan is required to start,

         *        0 in case the scan is required to start immediately

         * @param axis the scan axis

         * @param sector the antenna sector (NORTH or SOUTH)

         * @param azimuth the azimuth (radians) at the beginning of the scan

         * @param elevation the elevation (radians) at the beginning of the scan

         * @param ra the RA (radians) at the beginning of the scan

         * @param dec the DEC (radians) at the beginning of the scan

         * @param feasible_time the closest time for the dewar positioner to be

         *        able to execute the scan.

         *

         * To clarity the interface behavior, let's see some examples.

         *

         * 1) starting_time=0: checkUpdating() returns True in case it is ready to

         *    start the updating right now, and sets feasible_time to 0.

         *    In case it is not ready, it returns False and sets feasible_time to

         *    the closest time required for the dewar positionre to be ready.

         *

         * 2) starting_time>0: let's supposte starting_time is 2 seconds in the future;

         *    in that case, if the dewar positioner is able to start the updating

         *    in two seconds, then it sets feasible_time=starting_time and returns True.

         *    In case it is not able to start the updating at starting_time, it returns

         *    False and sets feasible_time to the closest time for the dewar positioner

         *    to be able to execute the scan.

         *

         * It raises ComponentErrors::ComponentErrorsEx in case of unexpected input

         * parameters, i.e. starting_time<0.

         *
