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 [[Title_list|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 [https://tools.ietf.org/html/rfc8536 RFC8536] for more information).

The conversion of a Tzif2 file to a TimeZoneRule structure is based on [https://github.com/eggert/tz/blob/master/localtime.c tz database code] with some custom modifications (Leap seconds aren't handled, no usage of "posixrules" and Tzif1 support stripped out).

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.

|}

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