Do what normal people do and never update those clocks. It’s not like +1/-1 math is hard, and I can’t imagine trusting a manually adjusted clock if I actually cared about the time
[citation needed]
I would think that changing clocks is actually the more "normal" thing to do.
The only clock I don’t change is my motorcycle because I can’t be bothered to use the archaic menu system to update something I never rely on.
That said, it does take me a few weeks usually to update all the clocks as I’ll only do it when it starts to bother me or if that specific clock contributes to me being late/early.
But I used to rely on my car's clock to know what time it is, and kept it updated for DST.
I'm sure you remember passwords, next to which the number 1 is quite easy to recall immediately. Don't make it complicated when it is easy.
