What Is The Reason Why Relying On The System’s Timezone Settings Is Not Safe With PHP’s Date()?

The warning message "date(): It is not safe to rely on the system’s timezone settings…" is displayed in PHP when the timezone is not set in the PHP configuration or code, and the system’s default timezone is being used.

To resolve this warning, you need to set the timezone explicitly in your PHP code or PHP configuration file. The warning message suggests using the date_default_timezone_set() function to set the desired timezone.

For example, to set the timezone to UTC, you can use the following code at the beginning of your PHP script:

date_default_timezone_set('UTC');

You can replace ‘UTC’ with any valid timezone identifier, such as ‘America/New_York’, ‘Europe/London’, etc., based on your needs.

By setting the timezone explicitly, you ensure that your script’s date and time calculations are accurate and prevent potential issues that may arise from relying on the system’s default timezone.
