[20.0.0+] Cmd13 now takes a total of 4-bytes of input instead of 8-bytes and returns a total of 2-bytes of output.
 
== GetTimeInSeconds ==
Same as [[#GetRtcTime|GetRtcTime]], but takes an input [[Bus_services#I2cDevice|DeviceCode]] ([[#bpc:r|bpc:r]] uses hardcoded value 0x3B000001).
 
== SetTimeInSeconds ==
Same as [[#SetRtcTime|SetRtcTime]], but takes an input [[Bus_services#I2cDevice|DeviceCode]] ([[#bpc:r|bpc:r]] uses hardcoded value 0x3B000001).
 
== SetResetOnShutdown ==
Takes an input bool '''DoReset''' and an input [[Bus_services#I2cDevice|DeviceCode]]. Similar to [[#SetUpRtcResetOnShutdown|SetUpRtcResetOnShutdown]], but this version assigns the provided boolean value on a per-client basis (instead of a global variable) and checks it when the current [[PSC_services#Power_Management_States|power state]] is '''ReadyShutdown'''.

Same as [[#ClearRtcResetDetected|ClearRtcResetDetected]], but takes an input [[Bus_services#I2cDevice|DeviceCode]] ([[#bpc:r|bpc:r]] uses hardcoded value 0x3B000001).
 
== EnableAlarm ==
Takes an input [[#Module|DeviceCode]], an input u32 '''RtcAlarmId''' (0 = RtcAlarm1, 1 = RtcAlarm2) and an u64 '''RtcAlarmTime'''. No output.
 
== DisableAlarm ==
Takes an input [[#Module|DeviceCode]] and an input u32 '''RtcAlarmId''' (0 = RtcAlarm1, 1 = RtcAlarm2). No output.

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).
