when to start/stop your light/darkness windows for flower

i have two questions about light schedule timing and I apologize if they are talked about elsewhere but I can't find anything.

1) when I go from 18hours light to 12hours light, what's the ideal way (or is there an ideal way) to cutoff the six hours?

Should I start the lights 6 hours later, turn them off 6 hours sooner, split the difference or does it even matter?

2) can you move the start/stop time of your light schedule? I don't mean change the duration of it, but say it turns on at 6am for 18 hours but you want to change it to go on at 8am for 16 hours.... will that cause noticeable stress on the plant?

My timer somehow got adjusted by over 90 min and I've been moving it back 15 min a day....

Just switch the timer to 12/12 according to the time you want to run the lights. It's not a big deal.
