Note that the BCM4710 does not support the wait instruction, this is not a mistake in the code. It originally comes from the OpenWrt patches.

The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up.

But it's really just an optimization so there is nothing wrong with just dropping the option (and whatever else goes along with it, I forgot all the nasty details) on the floor if due to a vintage compiler it can't be suported.
