Closed Unassigned: Datetime is 1 day off [9497]

Greetings,

I'm trying to write a datetime to a cell using ClosedXML. I set the IXLCell DataType to be XLCellValues.DateTime, and the value to be a new DateTime. I also set the number format id to 14 (mm/dd/yyyy)

When I look at the excel sheet, the date displayed is always one day larger than anticipated. When I read the cell value using ClosedXML (in a unit test), the value read from the file matches the value I wrote, but the actual excel sheet does not show the correct value.

Is this a bug in ClosedXML or am I missing something?

Thanks!
