The operation reads the log records in the log sequentially starting from any given time. The fromTime parameter indicates which time to start from. The howMany parameter indicates how many log records to retrieve, and the sign of the
howMany parameter indicates the direction (positive for forward retrieval or negative for backward retrieval). The log records are returned as a sequence.

Operation Exceptions:
1. NOT_IMPLEMENTED - If EMS does not support this operation.
2. INTERNAL_ERROR - Raised in case of non-specific EMS internal failure.
3. INVALID_INPUT - Raised when input parameter is incorrectly formed.
