/**
 * @brief PvrManager::CreateTask
 * Schedule channel recording task.
 *
 * @param url address of the stream that will be recorded (http://..., rtp://..., udp://...)
 * @param fileName full file name of recording (/media/USB-... or /ram/media/USB-...)
 * @param startTime recording start time
 * UTC time in "YYYYMMDDThhmmss" format or number of seconds since Epoch (1970/01/01 UTC)
 *
 * @param endTime recording end time
 * UTC time in "YYYYMMDDThhmmss" format or number of seconds since Epoch (1970/01/01 UTC)
 *
 * @return unique task identifier if operation was successful, otherwise return value is a string representing error code (<0) from error codes table
 *
 * @example
 * // number of seconds since Epoch can be obtained via Date object
 * var date = new Date();
 * var startTime = date.getTime()/1000;
