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.

Set following value in php.ini file

date.timezone = 'Asia/Kolkata'

It depends on your timezone. Set your timezone in php.ini

SQLSTATE[HY000]: General error: 1364 Field doesn't have a default value

Solution :

Go on mysql prompt and run following command.

mysql> SET GLOBAL sql_mode=''

Make sure no value has been set for attribute sql_mode in the file my.cnf.

mysql default current_timestamp error

The DEFAULT CURRENT_TIMESTAMP support for a DATETIME (datatype) was added in MySQL 5.6.

It is now possible to achieve this with DATETIME fields since MySQL 5.6.5

Previous versions can't do that with DATETIME.But you can do it with TIMESTAMP.

Upgrade your mysql with this version and you will not get this error again.
