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).
