| Difference (in nanoseconds) between UTC server time and RTC time. Updated by [[Friend_Services|the Friends sysmodule]] after every [[Online_Play|NASC]] login. Used by System settings to calculate the real current time according to the online play authentication server, in order to determine the user's actual age based on the given date of birth (related to COPPA, since this is used to check whether the user is at least 13 years old).

While the user name is NULL-terminated, the terminator is not applied when the user name is 10 characters long, which leads to online access breaking (002-0109) and buffer overflows when the user name is retrieved, even in DS games.
