Scheduling between the two
Working hours overlap from 9:00 am to 3:00 pm ART, which is 12:00 pm to 6:00 pm GMT. Anything inside that window falls in the normal working day at both ends.
Greenwich Mean Time (GMT) is used in as a fixed UTC+0 offset. Note that the UK itself leaves GMT every summer — see British Time below.
