My assumption is that this was a function of the change to PDST....At 1825 local, there was NO RFI noise heard at 6.990 mHz.  Nor was there any noise at 1925 local when the street lights came on....

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.
