RTC Time Date out of the box feature request

[cederom]

Is your feature request related to a problem? Please describe.

• Currently there is no Time Date framework in Zephyr. We need to create by hand this functionality.

Describe the solution you'd like

• Time Date functionality with full POSIX support.
• Time Date set to match current time.
• Time Date is preserved across reboot/reset (edit: mandatory).
• Edit: small RAM footprint (not necessarily POSIX may be internal).
• Edit: Unix Epoch timestamp integer (or better uint64_t) is minimal requirement and most of cases enough, also ISO8601 datestring in UTC/ZULU would be nice to have :-)

Describe alternatives you've considered

• I am using nRF52 chip and NRF SDK or POSIX+uptime functions to use RTC "by hand", but this is not preserved across reboot.

Additional context

• Common OS Time Date seems very important functionality not only for basic functions but also from a security standpoint.

Please consider implementing. Thank you :-)

I was also looking exactly for such a feature. I'm coming from Linux where I used stime() from std C Lib to set system time and sync it to hwclock. I would appreciate to see something similar in Zepyhr in the future.

What is the plan to move this forward?
Can someone share? I can put a PR.

#52618 has taken the first step here by implementing an RTC driver framework.

Still missing is the integration with POSIX time functions, and of course actual drivers for RTC peripherals.

I have moved to NuttX RTOS some time ago so not relevant for me anymore. If not implemented yet then not relevant for anyone else. Closing. Thanks :-)

Please reopen, just because you don't use Zephyr anymore doesn't mean the issue has fixed itself.

[cederom]

Ah, it was not completed, true :-)
