EndRunX (Extended)
Format
The EndRunX format is identical to the EndRun format with the addition of two fields - the cur-
rent leap second settings and the future leap second settings. The following string is sent once each
second:
T YYYY DDD HH:MM:SS zZZ m<CR><LF>
T is the Time Figure of Merit (TFOM) character described in
Appendix E - TFOM
.
This is the “on-time” character.
YYYY is the year
DDD is the day-of-year
: is the colon character (0x3A)
HH is the hour of the day
MM is the minute of the hour
SS is the second of the minute
z is the sign of the offset to UTC, + implies time is ahead of UTC.
ZZ is the magnitude of the offset to UTC in units of half-hours.
Non-zero only when the Timemode is Local (see Chapter 5).
m is the Timemode character and is one of:
G = GPS
L = Local
U = UTC
CC is the current leap seconds value.
FF is the future leap seconds value.
<CR> is the ASCII carriage return character (0x0D)
<LF> is the ASCII line feed character (0x0A)
NENA Format
NENA is the National Emergency Number Association. This organization has adopted a format for
use in PSAPs (Public Safety Answering Points). This format follows:
<CR><LF>Q DDD HH:MM:SS dTZ=XX<CR><LF>
Q is the time quality indicator and may be either:
<space> ASCII space character (0x20) which indicates locked.
? ASCII question mark (0x3F) which indicates the unsynchronized condition.
This is the “on-time” character.
DDD is the day-of-year
: is the colon character (0x3A)
HH is the hour of the day
MM is the minute of the hour
SS is the second of the minute
d is the DST indicator (S,I,D,O).
TZ=XX is the time zone where XX is 00 through 23
<CR> is the ASCII carriage return character (0x0D).
The first <CR> is the on-time character.
<LF> is the ASCII line feed character (0x0A)
