Takes an input s32 LocationName_index and a type-0x6 output buffer for #LocationName, returns an output s32 for total output entries.

LocationName

This contains a TimeZone location string with a max size of 0x24 bytes.

TimeZoneRule

This is an 0x4000-byte struct. Official sw uses fixed-size 0x4000 for the buffer size with the above commands.

This is loaded from the TimeZoneBinary title with the specified LocationName under the zoneinfo/ directory, the content is then converted into this TimeZoneRule structure.

The files contained under zoneinfo/ directory are Tzif2 files without Tzif1 header and data at the begining of them (see RFC8536 for more information).

The conversion of a Tzif2 file to a TimeZoneRule structure is based on tz database code with some custom modifications (Leap seconds aren't handled, no usage of "posixrules" and Tzif1 support stripped out).

notif:a

This is "nn::notification::server::INotificationServicesForApplication".

This was added with [9.0.0+].

Cmd Name
500 #RegisterAlarmSetting
510 #UpdateAlarmSetting
520 #ListAlarmSettings
530 #LoadApplicationParameter
540 #DeleteAlarmSetting
1000 #Initialize

RegisterAlarmSetting

Takes a type-0x15 input buffer #AlarmSetting and a type-0x5 input buffer. Returns an #AlarmSettingId.

The second buffer can be empty (addr=0/size=0). This is the ApplicationParameter.

Before using the cmd, sdknso uses hid IsFirmwareUpdateNeededForNotification then if needed launches the controller-applet for firmware-update.

After using the cmd when it failed, ShowError will be used when the Result is in a certain range, otherwise this will assert.

UpdateAlarmSetting

Takes a type-0x15 input buffer #AlarmSetting and a type-0x5 input buffer. No output.

The second buffer can be empty (addr=0/size=0). This is the ApplicationParameter.

ListAlarmSettings

Takes a type-0x6 output buffer to receive an array of #AlarmSetting. Returns a s32 AlarmSettingsCount.

LoadApplicationParameter

Takes an input #AlarmSettingId and a type-0x6 output buffer containing the ApplicationParameter. Returns an u32 actual_size.

DeleteAlarmSetting

Takes an input #AlarmSettingId.

Initialize

Takes a PID-descriptor and an input u64 pid_reserved.

notif:s

This is "nn::notification::server::INotificationServicesForSystem".

AlarmSettingId

This is "nn::notification::AlarmSettingId". This is an u16.

AlarmSetting

This is "nn::notification::AlarmSetting". Total size is 0x40 bytes. When initializing this to the defaults, the entire struct is cleared then the last 0xE-bytes are set to 0xFF.

Offset Size Description
0x00 0x02 #AlarmSettingId
0x02 0x01 Kind (0 = WeeklySchedule)
0x03 0x01 Muted
0x04 0x04 Padding
0x08 0x10 UID
0x18 0x08 ApplicationId
0x20 0x08 Not set by sdksno, besides clearing it during initialization.
0x28 0x18 Alarm schedule (WeeklyScheduleAlarmSetting)

Schedule:

Offset Size Description
0x00 0x0A Not set by sdksno, besides clearing it during initialization.
0x0A 0xE(7*2) Array of 7 entries where each entry is 2-bytes. Index is nn::time::DayOfWeek, Sun-Sat.

Array entries:

Each byte is set using an input s32. An entry with value 0xFFFF (the default) indicates that it's disabled. The high byte is the hour, the low byte is the minute. This uses local-time.

sdknso checks whether an entry is enabled with: return ({last 5-bits of the entry} < 3) && ((entry & 0xfc) < 60);. The first check is equivalent to comparing the second entry byte with value 24.
