Are there any potential pitfalls in using the strtotime function to manipulate timestamps in PHP?

One potential pitfall of using the strtotime function in PHP is that it may not always handle date formats consistently across different environments or locales. To ensure accurate timestamp manipulation, it's recommended to explicitly specify the date format when using strtotime. 

$dateString = '2022-01-01';
$timestamp = strtotime($dateString);
// Potential pitfall
echo date('Y-m-d', $timestamp); // Output may vary

// Solution: Specify date format
$timestamp = strtotime($dateString);
echo date('Y-m-d', $timestamp); // Always outputs '2022-01-01'
