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).

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). Size must be <=0x400. This is the ApplicationParameter.

A maximum of 8 Alarms can be registered by an Application at the same time.

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). Size must be <=0x400. 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.

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.
