[SOLVED] Resource allocation time error

Hi,
I am facing an issue when editing any resource allocation or adding resource allocation. When I checked the log file it is showing the following error lines, Please guide me to solve this.

2022-03-15 14:30:18.038 ***** ERROR ***** [V9.4.3] on file 'E:\wamp\www\projeqtor\tool\projeqtor.php' at line (3432)
2022-03-15 14:30:18.038 ***** ERROR ***** [V9.4.3] cause = mktime(): Epoch doesn't fit in a PHP integer

Thank you for quick response, I tried same as you suggested but error showing with just line changed only as following :2022-03-15 15:57:45.670 ***** ERROR ***** [V9.4.3] on file E:\wamp\www\projeqtor\tool\projeqtor.php' at line (3434)2022-03-15 15:57:45.671 ***** ERROR ***** [V9.4.3] cause = mktime(): Epoch doesn't fit in a PHP integerPlease find lines as following what I have done as per your instruction:
//  $dStart=mktime(0, 0, 0, $tStart[1], $tStart[2], $tStart[0]);
//  $dEnd=mktime(0, 0, 0, $tEnd[1], $tEnd[2], $tEnd[0]);

$dStart=mktime(0, 0, 0, intval($tStart[1]), intval($tStart[2]), intval($tStart[0]));
$dEnd=mktime(0, 0, 0, intval($tEnd[1]), intval($tEnd[2]), intval($tEnd[0]) );

Thanks, let me try & will respond whatever is the result.

I had chosen PHP version 8.0.13, changed the version to 7.4.26 & it worked fine.
