There's a whole protocol for doing exactly this. It's the time zone database/tz/tzinfo and is regularly updated for this very reason. Lots of countries and regions fiddle with their time on a regular basis and every major operating system has been able to accommodate it for decades. You can see a long discussion about managing DST or lack thereof in Egypt and Lebanon in the associated mailing lists just this month.

tzinfo updates usually are packaged into broader OS updates. Getting the right time is just a matter of running Windows Update or whatever other update utility you use. You can even check out the list of all of the DST-specific updates that Microsoft has done here.

The scale on the cost per eyeball is tiny - it might help to make it CPM (cost per thousand)?

They really overexpanded and tried to get into single-family markets that they couldn't serve economically; unfortunately, they're in really bad financial straits right now.

One interesting possibility that this might enable is for the city (or cities - they're in a number of markets) to pick their assets up for really cheap. It'd facilitate continuation of service and could serve as a jumping off point for community internet.

One interesting note here is that Starry (a Boston-based WISP) is suffering serious financial trouble right now, and it may be possible for the city to pick their assets and staff up seriously on the cheap.
