Time Services Requirements Scrub

[skliper]

Is your feature request related to a problem? Please describe.
TIME requirements out of date

Describe the solution you'd like
Update requirements.

NOTE 1 - this is not major reworking of the requirements/design (#302), but focused on just bringing the requirements up to date. Future issues will address significant development/rework.

NOTE 2 - MET functionality still applies here (not all abstracted to PSP) to support the virtual MET capability (hardware MET is not required).

Describe alternatives you've considered
N/A

Additional context
Summary of changes (w/ links if individual issues exist already):

• cTIME2000- HK requirement not consistent (update wording)
• cTIME2001 - wording scrub, remove "time server and time client" inconsistent pattern
• cTIME2002 - wording scrub, remove "time server and time client" inconsistent pattern
• cTIME2007 - Update summary, it's really compute SCTF given current time
• cTIME2008 - adjust CTF requirement (delete, redundant with add/subtract requirements)
• cTIME2010 - summary: select tone signal source, of PRIMARY vs REDUNDANT (although not explicitly defined), SetSignalCmd
• cTIME2012 - force to flywheel (not just flywheel), then will not update time based on Tone Data/Signal.
• cTIME2012.1 - propagates MET locally (update wording), uses internal best guess for MET.
• cTIME2013 - remove "second and subsecond", overdetailed and wrong, really SCTF
• cTIME2014 - remove "second and subsecond", overdetailed and wrong, really SCTF
• cTIME23XX - all requests remove extra language (format specified)
• cTIME2701 - time at tone window not handled by TS (delete, hardware), sent by request/cmd
• cTIME2702 - update MET (delete generic functionality requirement, PSP/hardware)
• cTIME2703 - MET resolution (delete, PSP/hardware)
• NEW API Requirements:
  • cTIME2315 - Provide time at tone message functionality given MET, provide in message like HK
  • cTIME2316 - Tone Data given GPS
  • cTIME2317 - Tone Data given Time
  • cTIME2318 - Register synch callback (callback at Tone Signal receipt)
  • cTIME2319 - unregister synch callback (UnregisterSynchCallback)
  • cTIME2320 - get clock info state flags for TIME (GetClockInfo)
  • cTIME2321 - convert a given MET to SC Time (MET2SCTime)
  • cTIME2322 - Local1HzISR, API to trigger 1 HZ processing
  • cTIME2323 - ExternalTone, API to trigger Tone processing
• NEW Cmd Requirements:
  • cTIME2012.2 - External Time Update Mode - Use Updates (update timekeeping when Tone Signal and Data pair are received)
  • cTIME2015 - ToneSendCmd just sends Tone Data message (no time update)
  • cTIME2016 - ToneData (Cmd), triggers receipt of Tone Data processing
  • cTIME2017 - ToneSignal (Cmd), triggers Tone signal processing
  • cTIME2018 - OneHz (Cmd), triggers 1Hz cycle processing
  • cTIME2019 - set MET, sets abstract MET (not hardware met), SetMETCmd
  • cTIME2020 - (AddDelayCmd)
  • cTIME2021 - (SubDelayCmd)
• NOTE: CFE2FSSeconds/FS2CFESeconds deleted per Deprecate/Delete CFE2FSSeconds and FS2CFESeconds #519
• NOTE: SetSourceCmd due refactor/fix per Time Services need cleanup relative to requirements #302
