help, light timer didnt work in flowering

my light is on 8pm to 8am during flowering this morning at 10am during the dark period i lost power and my light by default came on and i only noticed at 5pm when i got home, i turned it off right away. whats the best way to proceed? im on day 10 of flowering, should I turn it on at 8 pm to 8 am as usual or should I change it to 5am to 5pm seeing as I turn ed it off at 5pm.

thanks everyone

anyone? i would need to know within the next hour or so.

Keep it on the same 8 to 8 schedule the plants more used to it than the recent 5 to 5
