MySQL 5.6 DateTime Incorrect datetime value: '2013-08-25T17:00:00+00:00' with Error Code 1292
'2013-08-25T17:00:00+00:00'


This is a valid iso-8601 datetime value, but it is not a valid MySQL datetime literal.  On that point, the developer is incorrect.

The documentation explains what ALLOW_INVALID_DATES does:


  Check only that the month is in the range from 1 to 12 and the day is in the range from 1 to 31.


In other words, 2013-02-31 would be a permissible date if allow_invalid_dates is set.  This option does not do anything when the date or datetime isn't even in a valid format for MySQL.

The +00:00 is the timezone offset from UTC.  In this case, the time expressed is in UTC, so the offset is zero hours, zero minutes.  

Your workaround would be to remove the STRICT_TRANS_TABLES from the sql_mode that is a default in the config file created during the MySQL 5.6 installation process... you need to carefully consider the implications of changing this, but it does allow the data to go in.
