--- Comment #1 from PJ Fanning <fannin...@yahoo.com> --- I added r1918499 which shows that if the cell has the date in number format, that the test seems to work. Dates are usually formatted as numbers in the underlying xlsx files - although this may have changed in more recent Excel releases. I have observed that if the cell has the date in string format, then the result is as the OP described. I'm not sure what changes should be made. The code in the POI function implementations is not complete and changes tend to break other use cases. Microsoft do not fully document what the functions are supposed to do and many functions have many differnt types of possible inputs. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
