standard time
Clock's default setting
Standard time is the official time established for a region, based on the mean solar time at a reference meridian.
Most places observe standard time during part of the year and shift to daylight saving time for part: We set the clocks back an hour when standard time resumes.
Standard time zones divide the globe into roughly hour-wide bands, though political boundaries create irregularities.
