Before you write about a time
Our times assume a flat horizon at sea level and standard refraction, rounded to the nearest minute, so a difference of a minute or two from another service is normal; the methodology page explains why. A difference of several minutes, or a time on the wrong civil date, is worth reporting: tell us the place, the date and the value you expected.
