Glossary of Terms 

Term 

Definition 

DST 

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. 

RCC 

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 

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.
