| ~~Settings~~ time ~~offset: newly set timestamp - rtc timestamp~~

| 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).

| u64, Current local friend code. Updated by the friends sysmodule when a local friends account is loaded with [[FRDA:LoadLocalAccount]] accordingly.

| ~~Same content as 0x0009000?~~ This ~~console-unique u64~~ is ~~used~~ by [[~~Cfg~~:~~GenHashConsoleUnique~~|~~GenHashConsoleUnique~~]]. It is ~~generated~~ by ~~<code>((0x3FFFFFFFF) &~~ LocalFriendCodeSeed~~) | (random16 << 48))</code>, where random16~~ is ~~generated~~ by [[~~PSPXI~~:~~GenerateRandomBytes~~|~~GenerateRandomBytes~~]]

| u64, Local friend code base value. This value is sent by the friends sysmodule to the friends gameserver during NEX account creation and serves as a means to find PIDs (and thus "online" friend codes) for other consoles' that were registered using [[FRDA:AddFriendOffline]] when those console(s) hadn't yet registered with the friends services at the time. The lower 34 bits are from [[Nandrw/sys/LocalFriendCodeSeed_B|LocalFriendCodeSeed]], and the upper 16 bits are from the LocalFriendCodeSeed counter (see below block, 0x90002). The remaining bits are left zero. This value is initialized as described by the CFG module when the LocalFriendCodeSeed part is zero. Used by [[Cfg:GenHashConsoleUnique|GenHashConsoleUnique]].

| ~~The first~~ two bytes ~~are~~ the ~~same random16 used~~ in ~~0x00090001~~. ~~The second two bytes are zeros~~.

| u16, Local friend code counter. This value is initialized by the CFG module alongside block 0x90001 to two random bytes generated by [[PS:GenerateRandomBytes]] and also serves as a component of that block. It is incremented by PTM and stored in MCU storage when PTM save data is formatted. Once incremented, upon reboot, PTM will use the counter stored in MCU storage to update the local friend code base value (block 0x90001). After updating the relevant configuration blocks, PTM sets the storage area reserved for the counter to 0.
