Problem: UNIX_TIMESTAMP() called for a expression of the TIME data type returned NULL. Inside Type_handler_timestamp_common::Item_val_native_with_conversion the call for item->get_date() did not convert TIME to DATETIME automatically (because it does not have to, by design). As a result, Type_handler_timestamp_common::TIME_to_native() received a MYSQL_TIME value with zero date 0000-00-00 and therefore returned "true" (indicating SQL NULL value). Fix: Removing the call for item->get_date(). Instantiating Datetime(item) instead. This forces automatic TIME to DATETIME conversion (unless @@old_mode is zero_date_time_cast).
