What are the potential pitfalls of relying on Excel solutions for time conversions in PHP?

Relying on Excel solutions for time conversions in PHP can lead to potential inaccuracies due to differences in how Excel and PHP handle date and time calculations. To ensure accurate time conversions, it's best to use PHP's built-in date and time functions for consistency and reliability. 

// Using PHP's date and time functions for accurate time conversions
$excelTime = 44197.5; // Example Excel time value
$unixTime = ($excelTime - 25569) * 86400; // Convert Excel time to Unix timestamp
$phpTime = date('Y-m-d H:i:s', $unixTime); // Convert Unix timestamp to PHP date format
echo $phpTime; // Output: 2021-10-15 12:00:00
