Solar clocks are consistent during the year because noon is always at local noon. They just stop telling time effectively early or later depending on the season (i.e. how long the sun is shining). You just measure time around noon and you are always accurate to local time (even the modern era navy did this). It only matters if you need to synchronize time from very far away, which ancient people didn’t really need to do do.

I mean in the sense of measuring hours. Is it a constant angle from noon to 13:00, for example?
Even the “local noon” would drift of you want you measure with constant hours of a24th of a day.
Within a margin of a few minutes (i think 15 minutes at the most).
We are talking about a matter 20 to 30 seconds here.
