Shit, I slept in for DST, but my girls didn't

Well I screwed up a bit. I thought I was being sooo smart getting a nice fancy high quality timer. It can hold a bazillion events in its memory and even be set to change its times based on the changing night sky or the rise/fall of the moon.

Unfortunately it was a bit smarter than me I'm afraid. You see it also knew about daylight savings time of course. My normal light period is 9 pm to 9 am. So last night when we went off daylight savings time (fall back), my timer automatically went back an hour. As a result, the lights went off at 9 am as usual and thus my girls got 13 hours of light instead of 12. So now what? Should I start their next light period at 9 pm, giving them a full 12 hours of dark but ultimately getting them an hour off of their original schedule, or start at 8 pm, keeping them at their original schedule but shorting them an hour of dark today?

In summary, what's the best light schedule given I've already given them an extra hour of light:
a.) 12dark, 13light, 12dark, 12light
b.) 12dark, 13light, 11dark, 12light
c.) 12dark, 13light, something else

Also, anyone got a feeling how likely this mistake is to screw up my girls?
Thanks!

how far into flowering are you? and i would vote for going back to the original schedule. if you only fucked up one hour on one night and the rest was all gravy then i wouldnt worry too much man. good luck tho

Dont sweat it it''ll be fine

alright thanks for the advice. I have been flowering for 4 weeks +1day

all u do is just set the timer back an hour thats all i did,they got an extra hour of sleep,it wont hut them,mine were prob like its about damn time we get to sleep in for once,u get to sleep in nonstop

yeah. an hour is no big deal i think. the power went out last night for almost an hour cause of a rainstorm. no biggie.
