Cmd Name
0 #GetRtcTime
1 #SetRtcTime
2 #SetUpRtcResetOnShutdown
3 #GetRtcResetDetected
4 #ClearRtcResetDetected

GetRtcTime

Same as GetRtcTime from bpc:r, but takes an extra DeviceCode, which bpc:r hardcodes to 0x3B000001 (max77620_rtc0) instead.

SetRtcTime

Same as SetRtcTime from bpc:r, but takes an extra DeviceCode, which bpc:r hardcodes to 0x3B000001 (max77620_rtc0) instead.

SetUpRtcResetOnShutdown

Takes an u8 DoReset and a DeviceCode. Similar to SetUpRtcResetOnShutdown from bpc:r, but this version assigns the provided boolean value on a per-client basis (instead of a global variable) and checks it when the current power state is "ReadyShutdown".

GetRtcResetDetected

Same as GetRtcResetDetected from bpc:r, but takes an extra DeviceCode, which bpc:r hardcodes to 0x3B000001 (max77620_rtc0) instead.

ClearRtcResetDetected

Same as ClearRtcResetDetected from bpc:r, but takes an extra DeviceCode, which bpc:r hardcodes to 0x3B000001 (max77620_rtc0) instead.

LoadLocationNameList

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).
