My family at home has to deal with all the changes, though.
I generally go by "rig time"-- whatever time zone I am in, and translate that to "home", "the folks' time", or "office time" as needed.
When I am working, I am working, when I am not, I am not.
There are two clocks on the wall at home and an assortment of alarm clocks, but those fall under my wife's purview--unless I am at home when the "change" happens. Generally, I am blessed with not having to pay all that much attention to a clock.
I am sorry to hear about your wife, the world is a poorer place for the loss of a good woman.
