Solusi “date.timezone” Error pada PHP: date(), It is not safe to rely on the system’s timezone settings

saya baru saja install php-fpm dan menjalankan phpMyAdmin dan files php ternyata muncul error warning timezone. Seperti nampak di bawah ini:

Warning: phpinfo():
 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 'America/New_York' for 'EST/-5.0/no DST' 
instead in /home/rahmatriyanto/www/localhost/tes.php on line 6

Setelah saya cek di berbagai referensi ternyata error ini disebabkan timezone belum disetting.
Untuk mengatasi masalah ini bisa dilakukan dengan menambakan
date.timezone = GMT di bawah [Date] pada file /etc/php.ini

Langkahnya seperti dibawah ini:

1. login terminal sebagai root
2. nano /etc/php.ini carai baris [Date]

   [Date]
   ; Defines the default timezone used by the date functions
   ; https://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
   ;date.timezone =
   
   ; https://www.php.net/manual/en/datetime.configuration.php#ini.date.default-latitude
   ;date.default_latitude = 31.7667
   
   ; https://www.php.net/manual/en/datetime.configuration.php#ini.date.default-longitude
   ;date.default_longitude = 35.2333
   
   ; https://www.php.net/manual/en/datetime.configuration.php#ini.date.sunrise-zenith
   ;date.sunrise_zenith = 90.583333
   
   ; https://www.php.net/manual/en/datetime.configuration.php#ini.date.sunset-zenith
   ;date.sunset_zenith = 90.583333

   Tambahkan date.timezone = GMT

3. service php-fpm restart

Semoga bermanfaat
