Definition

Daylight saving time (DST) or summer time is the

practice of advancing clocks during the lighter months so

that evenings have more daylight and mornings have

less. Typically clocks are adjusted forward one hour near

the start of spring and are adjusted backward in the

autumn.

A radio-controlled clock is a clock that is synchronized

by a time code bit stream transmitted by a radio

transmitter connected to a time standard such as an

atomic clock.

WWVB is a NIST time signal radio station near Fort

Collins, Colorado. WWVB is the station that

radio-controlled clocks in most of North America use to

synchronize themselves. The 70 kW ERP signal

transmitted from WWVB is a continuous 60 kHz carrier

wave, the frequency of which is derived from a set of

atomic clocks located at the transmitter site, yielding a

frequency uncertainty of less than 1 part in one trillion.
