phpExcel xls 到 csv 的转换正在将日期更改为原始数据

Question

my function to convert xls file to csv using phpExcel is changing the value in the date field to raw. How do I avoid this from happening?

The function is as below

function convertXLStoCSV($infile,$outfile)
{
    $fileType = PHPExcel_IOFactory::identify($infile);
    $objReader = PHPExcel_IOFactory::createReader($fileType);

    $objReader->setReadDataOnly(true);   
    $objPHPExcel = $objReader->load($infile);    

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
    $objWriter->save($outfile);
}

The date in the xls file is of the format: 16.01.2017 00:00:00
The output csv file has the date in the format: 42751.0104166667

I have tried to change in file /Classes/PHPExcel/Style/NumberFormat.php

        self::$_builtInFormats[22] = 'm/d/yy h:mm'; 
        changed to 
        self::$_builtInFormats[22] = 'mm.dd.yyyy hh:mm:ss';

But this is not doing the magic

Your problem is

$objReader->setReadDataOnly(true);  

which is explicitly telling PHPExcel to read the cell data as raw data, without any of the styling information (such as number format masking).

Simply comment out that line
