Folks, we are using the new Pentaho methods for creating a de-identified data 
warehouse from multiple OpenMRS servers. One question that came up was the need 
to date-shift all dates in a patient record during the export. This requires 
saving a date shift factor (-15d to +15d) in the OpenMRS database to be used 
repeatedly when exporting data. This information should not be visible to the 
average user. Does it make sense to have a separate table with the patient_id 
and date_shift_factor that does not appear in the UI, or can it be appended to 
an existing patient table but not be accessible such as a person_attribute 
would be?

Thanks,
Andy
