Changes to PDR properties and the mdex:time data type may affect the ingest of your attribute schema and source data.
The mdex:time data type now requires a time zone. In version 7.4.x, a time zone was not allowed as part of the time representation. In 7.5.x, a time zone is required for both time formats: either a universal (UTC) time or as a local time plus a UTC time zone offset. For details on the mdex:time formats, see the Oracle Endeca Server Data Loading Guide.
