What are the best practices for error handling and fallback mechanisms in PHP scripts that rely on time-based logic?

When working with time-based logic in PHP scripts, it is important to implement error handling and fallback mechanisms to ensure the script continues to function correctly even if there are issues with time-related functions or dependencies. One way to handle errors is by using try-catch blocks to catch exceptions and provide fallback logic in case of failures.

try {
    // Time-based logic code here
} catch (Exception $e) {
    // Fallback logic in case of errors
    // Log the error or notify the developer
    // Implement alternative logic if necessary
}
