Scheduling between the two

Working hours overlap from 5:00 pm to 6:00 pm SGT, which is 9:00 am to 10:00 am 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.
