Birth control pill+time change

I’m getting a tubal in a couple weeks so my dr started me on a pack of pills meantime.

So I have been taking it at 5:15 normally, but with the time change when do I take it?

I ended up taking it at 4:15 today because my car said it was still 5:15 ( forgot to change it ) and this all sounds confusing but when do I take it now?! 4:15 or 5:15?! Idk how this works with time change lol!
