HI, All

Is it possible to have not-super-sharp-clock using TimeNIST (get time, say, one time per week) and RTC timer and memory to calculate the current time after DeepSleep ?
Experimenting with RTC-memory read-write i found that "RTC time" from system_get_rtc_time() function after returning from DeepSleep is always Get rtc time around values of 12000......16000.
I cannot understand - if the module is power up, but use DeepSleep periodically - the RTC timer should go on all the time, and return bigger values ...
Or i do not understand something... how to use correctly DeepSleep and calculate time of this sleeping ?

But why RTC time after DeepSleep is not proportionally bigger than before ? No more than ~16000.
I guessed, it should tick all the time while powered up. And if 1 min in DeepSleep - after resume the value should be > 60 seconds

Hmmm, yes, as in those example, how another, most of native functions in B4R we use via inline C.

You can get time from NIST with the limit that it must be not less than once in 4 seconds. I have a clock running with getting time from Nist every few minutes and a timer of 1 second to advance the time, not RTC. After wake up get time from NIST and continue.
