date offset by 1 day (date décalé d'un jour)

```
for those who have the problem of date, offset by 1 (eg 18/10/2011 10/19/2011
affcihe), so I think I found the solution:
go to file: read.php:

$utcValue = round(($utcDays+1) * SPREADSHEET_EXCEL_READER_MSINADAY);
change it on:
$utcValue = round(($utcDays) * SPREADSHEET_EXCEL_READER_MSINADAY);

pour ceux qui ont le problème de date qui est décalé de 1 (exemple:

$utcValue = round(($utcDays+1) * SPREADSHEET_EXCEL_READER_MSINADAY);
change le au:
$utcValue = round(($utcDays) * SPREADSHEET_EXCEL_READER_MSINADAY);

Start in read.php at the SPREADSHEET_EXCEL_READER_MSINADAY calculation and trace how Excel dates are converted to displayed dates. Reproduce the one-day offset with the reported example, then verify the corrected conversion against additional date values and confirm the displayed dates are accurate.
