I ran the test suite using 32-bit PHP. There were 2 places where changes were needed due to 32-bit timestamps. Reader\\Xml.php was using strtotime as an intermediate step in converting a string timestamp to an Excel timestamp. The XML file type stores pure timestamps (i.e. no date portion) as, e.g., 1899-12-31T02:30:00.000, and that value causes an error using strtotime on a 32-bit system. However, it is sufficient to use that value in a DateTime constructor, and that will work for 32- and 64-bit. There was no test for that particular cell, so I added one to the XML read test. And that's when I discovered the getFormattedValue bug. The cell's format is `hh":"mm":"ss`. The quotes around the colons are disrupting the formatting. PhpSpreadsheet formats the cell by converting the Excel format to a Php Date format, in this case `H\:m\:s`. That's a problem, since Excel thinks 'm' means *minutes*, but PHP thinks it means *months*. This is not a problem when the colon is not quoted; there are ample tests for that. I added my best guess as to how to recognize this situation, changing `\:m` to `:i`. The XML read test now succeeds, and no other tests were broken by this change. Test Shared\\DateTest had one test where the expected result of converting to a Unix timestamp exceeds 2**32. Since a Unix timestamp is strictly an int, that test fails on a 32-bit system. In the discussion regarding recently merged PR #1870, it was felt that the user base might still be using the functions that convert to and from a timestamp. So, we should not drop this test, but, since it cannot succeed on a 32-bit system, I changed it to be skipped whenever the expected result exceeded PHP_INT_MAX. There are 3 "toTimestamp" functions within that test. Only one of these had been affected, but I thought it was a good idea to add additional tests to the others to demonstrate this condition. In the course of testing, I also discovered some 32-bit problems with bitwise and base-conversion functions. I am preparing separate PRs to deal with those.

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
