Shows the error message similar to the following in console: err coapi: [error] [client] PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /var/sam/www/admin/reports/index.php on line 8, referer:


There is no functional impact to APM or the BIG-IP system.


When you click on the GUI's session page, the error shows up in the console.


None. This is cosmetic.

Fix Information

The system now uses the correct timezone, so no error occurs when clicking on the GUI's session page.
