nrf_cal_set_time setting issue for 2100 year...

[edmond.yun]

Hello, 

I am using the following code to set time in my code, but when trying to set 2100 year or 2040 more year with nrf_cal_set_time function,

it is failed, it shows the strange time in all value like year/month/day/time(hour so on). why ?

Could you please kindly help to let me know the reason and solution ?

I used RTC 0 and the following setting : 

// <e> RTC_ENABLED - nrf_drv_rtc - RTC peripheral driver
//==========================================================
#ifndef RTC_ENABLED
#define RTC_ENABLED 1
#endif

#ifndef RTC0_ENABLED
#define RTC0_ENABLED 1
#endif

#ifndef CLOCK_CONFIG_XTAL_FREQ
#define CLOCK_CONFIG_XTAL_FREQ 1
#endif

#ifndef CLOCK_CONFIG_LF_SRC
#define CLOCK_CONFIG_LF_SRC 1
#endif

thankful for your support in advance,

thanks.

You believe your battery will last till 2040?

It may be related to the Unix timestamp overflow at 2038 Jan 19th: https://www.unixtimestamp.com/

Hi, Matt,

firstly thankful for good information. I think that I can't solve the issue in 32 bit system,

Could you please kindly help to let me know whether my opinion is right or not ?

thankful for your support in advance,

thanks.

I believe the client's requirement is more important than our "opinions". Does your client require a timestamp beyond 2038?
