[webservices] New versions of ws-bulkdataselect, ws-dataselect and ws-timeseries webservices

[Bruce Weertman]

Hello webservice users,

The DMC has updated it's ws-bulkdataselect, ws-dataselect and ws-timeseries webservices

http://www.iris.edu/ws/bulkdataselect
http://www.iris.edu/ws/dataselect
http://www.iris.edu/ws/timeseries

User's of the DMC's FetchBulkData script should update to the latest version if you wish to select
data with microsecond resolution, older versions should continue to work as usual if microseconds
are not specified.

Users of the DMC's IRIS-WS library or MATLAB irisFetch.m are not effected.

Changes include:

-----------------------------------------
Microsecond time resolution
-----------------------------------------
Time limits may now include microsecond resolution, matching the resolution of the SEED data
in the DMC archive.  Previous versions only supported millisecond time resolution.

This change allows selections to be specified at the sample level in all cases.  For example,
all samples on day 2004-12-26 are selected with the following start and end times:

   2004-12-26T00:00:00 2004-12-26T23:59:59.999999

This also allows users to break very large requests into smaller requests which can be
reassembled on the users end without generating gaps or overlaps.

--------------------------------------------------
Better handling of near realtime data
--------------------------------------------------
This change only effects ws-dataselect and ws-timeseries

Refreshing queries which are near realtime (i.e. cover time ranges close to the present time)
will more reliably result in newer and more current data sets being returned.
Previous versions held data cached for an hour or more.

-------------------------------------
Internal logging changes
-------------------------------------
We now better track returned http status codes to better help identify system problems

regards,
IRIS DMC web services team
