see this

https://github.com/micropython/micropython/blob/b33f108cdeb57c9d84e5a4eff5a46aa49c6dd558/ports/esp32/modutime.c#L52

and this

https://github.com/micropython/micropython/blob/b9ec6037edf5e6ff6f8f400d70f7351d1b0af67d/ports/esp32/machine_rtc.c#L105

I know it seems to have been designed, but if I assign values like this, I won't be able to use the following code.

machine.RTC().datetime(time.localtime(546450051)) # 546450051 only a number.

Is there a better way to set seconds to RTC time.

Otherwise I'll fill in the third element to align the structures, is that so?

The fields expected by the esp32 implementation differ from those
described in the documentation for machine.RTC.init.

See e.g. #4540 for people who have run into this issue.
