This method replaces the values and qualities in the history database at the specified timestamps for one or more items. If no value exists at the specified timestamp, the new value shall not be inserted; instead errors shall indicate an error. This method is intended to replace existing values at the specified timestamp; e.g., correct lab data that was improperly processed, but inserted into the history database. The serverHnd, timeStamps, dataValues and qualities are arrays of equal size. To replace the values for a number of different items at a single time, then timeStamps array would have the same time for each item. To replace a stream of values, timestamps and qualities for a single item, set the size of the item array to the number of values to be replaced and put the same ItemID in each element.
