Is the library safe to use after the year 2038?

I noticed that STM32CubeIDE allows you to use a 64-bit variable, I would like to know if the time.h library is already updated with a 64-bit variable.

That depends on what system library are you using.

Thanks,

Does this mean that What comes with STM32CubeIDE 1.4.1 is already safe from the year 2038 problem?

I don't know what comes with CubeIDE, I don't use it.

You're the developer, use the libraries that meet or exceed your expectations.

Use your own tested/validated code for things which are critial.​

Not sure the RTC is rated beyond 2099​
