If it is a simple timer that doesn't "know about" DST, it would "appear" to
shift to one hour later (in local PDT) if there were no human intervention. If
the human was "confused" and/or didn't know or properly interpret the "Spring
ahead, Fall back" hint, s/he might have set the timer in the WRONG direction by
an hour. The combined effect of that mistake coupled with the ,change to PDT
would result in the two-hour delay you observed.
My guess is that within a day or three, the error will be corrected, and your
noise will return at about 6:25 p.m. PDT.
