My New Countdown 'til Boston

I visited Mike Power's Love2RunCanada blog and admired his countdown timer. He invited me to copy it, so I installed it and was immediately puzzled by the apparent appearance of an incorrect time. Then it struck me, the differential of an hour was appearing in order to compensate for the transition tonight to daylight saving time. I got it installed, and it seems to be working OK...but Mike's clock differs from mine by two hours. Now, I'm trying to figure out if Mike manually compensated for both daylight time and his being on Atlantic Time (versus the Eastern Time) that I, along with Boston, am on. I think a brief discussion with Mike is in order. Thank you, Mike, for your support.
