(By definition) for DA9063 I was trying to be rigorous. The .read_time function is slightly different here because I can make a copy the alarm time into the RTC time structure to solve an RTC synchronisation problem internally to the DA9063. https://elixir.bootlin.com/linux/v4.5.6/source/drivers/rtc/rtc-da9063.c#L253 But after some further looking, I have not got any explicit case of how the time read directly from the DA9063 registers can be incorrectly represented. So there should be no need to check this. Regards, Steve
