SYMPTOM
In Strategy 9.4.1 and 10.x date values older than 12/31/1899 stored in an Oracle database are displayed on reports as time only in Strategy Developer as shown in the image below:

CAUSE
Older dates than 12/31/1899 get represented using negative numbers. Strategy Developer can not display such negative numbers for dates and are therefore displayed as times. Dates starting from 1/1/1900 can be represented in correctly in Strategy Developer.
ACTION
Use Strategy Web to execute reports with dates older than 12/31/1899.
