*Rolls on the floor laughing*.. Actually having the correct time with a predictable offset of minutes is not a bad idea... He isnt the first, nor the last who sets their clock 5-10 minutes *ahead*... or behind (if they are the early type) but keeping it under control (no more than 10 min)..But it definitely should do something to the time set menu in the UI that says Hello im tampered with, perhaps change the color of the set arrows or something in the clock set menu if this is enabled..
Don't believe in completely undoing the clock drifting fixes because at least this is a predictable (fuzzy error).. not an unintentional one. plus technically the time would still be accurate, it would just be a different offset.. kinda like my router which doesnt autoset Dst (eugh)
