I handled it by moving to Arizona - no DST here.
On my secondary TV, I have a VCR that I bought in 1994. It has no DST override, so every Spring, on the 1st Sunday in April, the clock would automatically jump ahead an hour, and I'd have to change it back. On the last Sunday in October, it would jump back an hour, and I'd have to set it ahead again.
I had the same problem last fall with Radio-Info. I wonder if they have that fixed now?
As for your computer, you might check to see if Microsoft and Apple issued OS patches to correct the DST change. Otherwise you'll have to reset your time manually this Sunday, then set it again on April 1st. You'll have the problem again in the fall, since DST now runs through the 1st Sunday in November instead of the last Sunday in October. If there is no patch, you may consider turning off the DST setting and taking care of the time change manually.
For recording devices that are set via signal from the TV stations, I doubt you'd have a problem, but if you're recording anything on Sunday, I'd double-check the time before you record.
