We recently ran into a problem with the tools we use to process LNDB data. We installed a development environment in Matlab 2015a, created a connection to LNDB using the JDBC to Windows SQL Server, opened the Database Toolbox in Matlab 2015a, clicked on a particular LNDB table, and clicked all.
The resulting output shows the date/record number pair displayed by Matlab offset back 2 days (with 5min data). Our production servers run Matlab 2013b and this problem is not present.
Just thought I'd post this hear in case anyone else is running a similar environment and interested in updating their matlab to 2015a. We do not currently have a solution for this except to migrate back to Matlab 2013b.
Update: This was a known problem in Matlab relating to the JDBC drivers at the time of communication.
A solution to this datetime offset maybe be found by following instructions posted online here: http://www.mathworks.com/help/database/ug/microsoft-sql-server-jdbc-windows.html
