RevisionDateWhoCommit message
76:c2035b7754fe 2020-07-27 andrewboyson Corrected haveFullTime in sync time PPS default tip
75:09d473b1a67f 2020-04-14 andrewboyson Removed bug whereby a difference of over 0.5 second prevented the governor from aligning the clock
74:9d336a47ab84 2020-04-08 andrewboyson Added 'CLK' in front of log messages. Gave some internal functions better names.
73:286a739f7c05 2020-02-27 andrewboyson Added a method to allow the UTC offset to be changed with a corresponding adjustment to TAI so that the resulting UTC time was not changed. This was used in the clock web page.
72:8f15a8b142ab 2020-02-27 andrewboyson Prevent clock from being set if only PPS is coming through; clock sets once PPS+NMEA or NTP is used.
71:f621d2127216 2020-02-26 andrewboyson Added initialisation for the case where the RTC has lost power
70:d04775a75597 2019-10-21 andrewboyson Minor tweaks to allow a pps signal with the time (in utc seconds)
69:4e48d3859b87 2019-10-18 andrewboyson Changed clkgovsync routines to accept an offset time in seconds rather than an absolute time.
68:807c1c7b2c22 2019-10-07 andrewboyson Include arm_compat.h to allow the use of the __[en/dis]able_irq intrinsics.
67:c44c5c90e35a 2019-09-27 andrewboyson Changed __disable_irq and __enable_irq to equivalent in line asm
66:466803ec48d0 2019-05-27 andrewboyson Moved all the timer , random and scan modules into the lpc1768 library
65:c48eb31e030d 2019-05-07 andrewboyson Moved RandomInit into ClockInit where it fits better with the random module being in the Clock library.
64:d1b9e47aa754 2019-04-12 andrewboyson Added random from lpc1768
63:28738aaad2a8 2019-03-21 andrewboyson Improved pro rata calculation of clktime
62:d382c178399e 2019-03-20 andrewboyson Renamed MsTimer functions to absolute, relative and repetitive to better reflect their purpose.
61:05bc814bf20b 2019-03-20 andrewboyson Introduced a delay timer and renamed the existing timer to interval
60:7e3185a6ffa6 2019-02-22 andrewboyson Modified gov.h int64 to clktime
59:070262625fb0 2019-02-22 andrewboyson Moved NTP conversion routines to net library
58:ad2bfd0345de 2019-02-21 andrewboyson Forgot to rename the end of some conversion routines from 'XxxxTimeT' to 'XxxxTime64'.
57:4daf2e423b27 2019-02-21 andrewboyson Two changes: defined typedef for clktime from int64_t; created new typedef time64 from int64_t to replace time_t to avoid the 2038 problem.
56:3e4fe2d3db4e 2019-02-21 andrewboyson Tidied formatting
55:e18983651004 2019-02-21 andrewboyson Optimised conversion between utc and tai.
54:a3c018ceca77 2019-02-21 andrewboyson Two changes:; Added method to governor module to allow pps to synchronise to the nearest second if the full time is not available.; Added UTC conversion to the governor synchronisation input and to the NTP timestamp conversions.
53:2605da6cf1c7 2019-02-13 andrewboyson Refactored the Ppb settings
52:333a0822a06d 2019-02-12 andrewboyson Refactered some gov setting names
51:826c58fbfaed 2019-01-10 andrewboyson Modified UTC concept from leap seconds to change to epoch
50:b804e93ccc1e 2019-01-09 andrewboyson Fixed bug in next leap second start time
49:e4424cc18bcb 2019-01-09 andrewboyson Improved handling of negative leap seconds (even if they will never happen)
48:b0f38e523552 2019-01-08 andrewboyson Corrected name of ClkUtcInit routine
47:fd2af868c10a 2019-01-08 andrewboyson Rearranged state into the owner modules. Renamed ClkSync to ClkGov.
46:d3d56cb47940 2019-01-08 andrewboyson Changed main name from clock to clk
45:1d8d5b312f72 2018-12-31 andrewboyson Added ClkSyncIsReceivingTime to allow display of whether an external reference is providing time for the clock to synchronise to (PPS for the GPS clock and NTP for others).
44:aa45226d118e 2018-12-29 andrewboyson Made TAI with conversion to UTC as required
43:45b11d2c5490 2018-12-05 andrewboyson Put explanatory text into the library page wiki instead of text files.
42:849060aec279 2018-12-04 andrewboyson update comments on chosen clock time format
41:8cd859cd1475 2018-12-04 andrewboyson Changed names to always start with Clk or Clock
40:53666b1a5848 2018-12-04 andrewboyson Renamed timer to hrtimer; added clktimer to handle utc based times.
39:5b594b1b6a0a 2018-12-03 andrewboyson Minor changes to names in timer
38:25b2a3c494aa 2018-12-02 andrewboyson Removed ClockTicked to force the use of the ms timer instead.; Also reintroduced time_t in the expectation that it will made unsigned or 64bit before 2038.
37:330b844f54b6 2018-12-01 andrewboyson Modified to remove dependence on time_t (32bit) and used an int64 instead.
36:6a8a8e1951d4 2018-12-01 andrewboyson Made the scan time routines separate
35:ba9f575aa3c6 2018-12-01 andrewboyson Tidied and separated the library into high res timer; low res tick counter rtc; tm local and utc; and clock folders
34:aeb58975e61a 2018-11-30 andrewboyson Corrected unsigned comparison in TimerIntervalHasElapsed.
33:b9e3c06e7dab 2018-11-30 andrewboyson Made clktime.c instead of tick.c; made tick.c for 20ms ticks. Lots of tidying.

26:0421132e6eaf 2018-01-25 andrewboyson Changed ticks from a count of ns to a fixed fraction of 30bits. This makes it much easier to convert to and from NTP and time_t
25:81014a201736 2018-01-22 andrewboyson Moved timer defines from tick to timer
24:6c9833e2a049 2018-01-22 andrewboyson Moved timer stuff into its own file
