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.
