Format 1
This format provides the fully decoded time data stream. Format 1 converts the received day of
year data (001-366) to a date consisting of day of week, month, and day of the month. Format 1
also contains a time synchronization status character, year, and time reflecting time zone offset
and DST correction when enabled. Format 1 data structure is shown below:
CR LF I ^ WWW ^ DDMMMYY ^ HH:MM:SS CR LF
where:
CR = Carriage Return
LF = Line Feed
I = Time Sync Status (space, ?, *)
^ = space separator
WWW = Day of Week (SUN, MON, TUE, WED, THU, FRI, SAT)
DD = Numerical Day of Month (^1-31)
MMM = Month (JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC)
YY = Year without century (99, 00, 01 etc.)
HH = Hours (00-23)
: = Colon separator
MM = Minutes (00-59)
SS = Seconds (00 - 60)
The leading edge of the first character (CR) marks the on-time point of the data stream.
The time synchronization status character I is defined as described below:
(Space) =
Whenever the front panel time synchronization lamp is green.
? =
When the receiver is unable to track any satellites and the time synchronization
lamp is red.
* =
When the receiver time is derived from the battery backed clock or set manually
through the Setup Port Interface.
Example:
* FRI 20APR01 12:45:36
The example data stream provides the following information:
Sync Status: The clock is not time synchronized to GPS. Time is derived from the battery
backed clock or set manually
