Do you reset your beardie's light timer during DST? Right now, I've got the lights on at 7 and off at 9... with DST this weekend, that would mean lights on at 8 and off at 10 if I don't reset them. I'm wondering if Figment would really notice either way...
They are set to come on 6am, and go off 9pm and I never change this. In my location 6am is the latest sunrise in the year ( mid winter ) and 9pm is about the latest end of dusk in mid summer.
It's very easy to adjust for DST on my electronic lamp timer ( I only need press the DST button ) , but I can't be bothered doing so.
Your dragon wont care, Figment will mostly be on her own internal clock and will be taking cues from your activities and natural light coming in.
