Mountain Time Zone
The
Mountain Time Zone
of
North America
keeps time by subtracting seven hours from
Greenwich Mean Time
, during the shortest days of autumn and winter (
UTC-7
), and by subtracting six hours during
daylight saving time
in the spring, summer, and early autumn (
UTC-6
). The clock time in this zone is based on the
mean solar time
at the
105th meridian west
of the
Greenwich Observatory
. In the United States, the exact specification for the location of
time zones
and the dividing lines between zones is set forth in the
Code of Federal Regulations
at 49 CFR 71.
