Flowering timer question

So I’m week 3/4 of flower lights on was 1 pm till 1 am. Based on what I was working now I’m not working that I wanted to switch it to lights on at 8 am to 8 pm. So last night I switched it to turn off at 11 and back on at 11am. And was gonna repeate in a day or so. But for some reason I left it to come on at 8 am. I’m just wondering if the 2 hours of early darkness last night and and 3 hours earlier making it only 9 hours of darkness. Will it mess anything up ?
it will be left on 8-8 for the rest of the run.
