kadonotakashi 0:8fdf9a60065b 25 This is the host part of the test to verify if:
kadonotakashi 0:8fdf9a60065b 26 - _rtc_mktime function converts a calendar time into time since UNIX epoch as a time_t,
kadonotakashi 0:8fdf9a60065b 27 - _rtc_localtime function converts a given time in seconds since epoch into calendar time.
kadonotakashi 0:8fdf9a60065b 28
kadonotakashi 0:8fdf9a60065b 29 The same algoritm to generate next calendar time to be tested is used by both parts of the test.
kadonotakashi 0:8fdf9a60065b 30 We will check if correct time since UNIX epoch is calculated for the first and the last day
kadonotakashi 0:8fdf9a60065b 31 of each month and across valid years.
kadonotakashi 0:8fdf9a60065b 32
kadonotakashi 0:8fdf9a60065b 33 Mbed part of the test sends calculated time since UNIX epoch.
kadonotakashi 0:8fdf9a60065b 34 This part validates given value and responds to indicate pass or fail.
kadonotakashi 0:8fdf9a60065b 35 Additionally it sends also encoded day of week and day of year which
kadonotakashi 0:8fdf9a60065b 36 will be needed to verify _rtc_localtime.
kadonotakashi 0:8fdf9a60065b 37
kadonotakashi 0:8fdf9a60065b 38 Support for both types of RTC devices is provided:
kadonotakashi 0:8fdf9a60065b 39 - RTCs which handles all leap years in the mentioned year range correctly. Leap year is determined by checking if
kadonotakashi 0:8fdf9a60065b 40 the year counter value is divisible by 400, 100, and 4. No problem here.
kadonotakashi 0:8fdf9a60065b 41 - RTCs which handles leap years correctly up to 2100. The RTC does a simple bit comparison to see if the two
kadonotakashi 0:8fdf9a60065b 42 lowest order bits of the year counter are zero. In this case 2100 year will be considered
kadonotakashi 0:8fdf9a60065b 43 incorrectly as a leap year, so the last valid point in time will be 28.02.2100 23:59:59 and next day will be
kadonotakashi 0:8fdf9a60065b 44 29.02.2100 (invalid). So after 28.02.2100 the day counter will be off by a day.
