Database time zone
The database timezone has times smaller by 8 hours and 0 minutes compared to the PHP timezone. These are the time zones compatible with the database one: Africa/Abidjan, Africa/Accra, Africa/Bamako, Africa/Banjul, Africa/Bissau, Africa/Conakry, Africa/Dakar, Africa/Freetown, Africa/Lome, Africa/Monrovia, Africa/Nouakchott, Africa/Ouagadougou, Africa/São Tomé, Americas/Danmarkshavn, Atlantic Ocean/Reykjavik, Atlantic Ocean/St. Helena, and Greenwich Mean Time (UTC)
Database should support the configured character set and collation
The database does not have a complete support for all the Unicode characters. This implies, for example, that you may not be able to save emoticons (it's the same behavior as concrete5 versions older than 8.5.0). You should upgrade your database to fix this issue.
