Format 8 includes a time synchronization status character, the four digit year, day of year, time
reflecting Time Zone Offset and DST corrections when enabled. Format 8 also includes the
DST/Standard Time indicator, and the Time Zone Offset value. Format 8 data structure is
shown below:
CR LF I ^ ^YYYY^ DDD ^ HH:MM:SS ^ D+XX CR LF or
CR LF I ^ ^YYYY^ DDD ^ HH:MM:SS ^ D-XX CR LF
where
CR = Carriage Return
LF = Line Feed
I = Time Sync Status (space, ?, *)
YYYY = Four digit year indication
^ = space separator
DDD = Day of Year (001 - 366)
HH = Hours (00-23)
: = Colon separator
MM = Minutes (00-59)
SS = Seconds (00 - 60)
D = Daylight Saving Time indicator (S,I,D,0)
XX = Time Zone Switch Setting (+/- 00 to 12)
The leading edge of the first character (CR) marks the on-time point of the data stream.
Time sync status character I is described below:
I = (space) when the NetClock is synchronized to UTC
source.
= * when the NetClock time is set manually.
= ? when the NetClock has not achieved or has lost
synchronization to UTC source.
The time and date can be set to either local time or UTC time, depending upon the configuration
of the output port.
