- No trimming of miniSEED records to requested time window — This FDSNWS implementation returns the records as available in its data source, e.g., SDS archive. It is guaranteed that the requested time range is within the returned data (if available in the archive) but not that it is exactly the requested time range. FDSNWS does not trim and therefore re-encode miniSEED records. The rationale for that is that miniSEED records are probably further distributed and stored in other archives and we do not see the point in modifying them. Furthermore we do not want to increase the load on the web server with that extra processing step.
