In the New Jersey when "day light saving time" do you adjust the UTM time zone under the local setting to adjust to it.

Or do we leave it at -5.00hr. ?

During Daylight Savings Time, those of us in the EAstern US will use -4, during Standard Time -5.

That way the observations in your Time Line will match your wristwatch. Much easier to figure out things.

or, do the sensible thing and forget the silly time zones

use a watch with a 2 zone feature and keep one set for UTM. Best advance in time keeping devices since the perfection of the ship's clock
