Values in date fields are converted to 12/31/1899 when exporting a shapefile or geodatabase feature class to a coverage.
This is a known issue.
Use ArcInfo Workstation to convert the data to coverage format.
If the data is a geodatabase feature class use ArcCatalog to export the data to a shapefile first.
- Start ArcInfo Workstation.
- Navigate to the workspace that contains the shapefile using the WORKSPACE command.
- Use the SHAPEARC command to convert the shapefile to a coverage.
