% Convert @var{datenums} from the Microsoft Excel date format to the
% format used by @code{datenum}. If set to 0 (default, Excel for
% Windows), @var{convention} specifies to use the Excel 1900 convention
% where Jan 1, 1900 corresponds to Excel serial date number 1. If set
% to 1 (Excel for Mac), @var{convention} specifies to use the Excel
% 1904 convention where Jan 1, 1904 corresponds to Excel serial date
% number 0.
%
% Note that this does not take into account the Excel bug where 1900 is
% considered to be a leap year unless you give the 'ExcelBug' option.
%
% Excel does not represent dates prior to 1 January 1900 using this
% format, so a warning will be issued if any dates preceed this date.
