misspelled the timezone identifier. We selected 'UTC' for '8.0/no DST' instead in"

date('Y-m-d H:i:s');

2. Use ini_set('date.timezone','Asia/Shanghai');

3. Modify php in the header. ini. Open php5.ini and search for date.timezone. Remove the semicolon and change it to: date.timezone =PRC

. Just restart the http service (such as apache2 or iis, etc.).

(in order Chongqing, Shanghai, Urumqi) Available in Hong Kong and Taiwan: Asia/Macao, Asia/Hong_Kong, Asia/Taipei (Macau, Hong Kong, Taipei in order), and Singapore: Asia/Singapore, of course PRC is also acceptable.
