Hi Fred, Time is a relative notion. In the north of Iceland maybe more than elsewhere. But, what is "too far off"? At the latitude of about 65 degrees the failure in time keeping of a sundial with a vertical gnomon and the hour markers equally spaced on a circle is no more than 10 minutes at march 21 or september 23 but can raise to 50 minutes at the solstices. At june 21 when the circular sundial is indicating 6 p.m. it is about 5.10 p.m. You can verify it by superposing the circular sundial on a analemmatic sundial designed for that situation.
