Notes
Any IRIG
that includes
current year,
other than
1344 or
C37.118
 No UTC
offset from
TAI
 No pending
leap
PTP:
 can't set TAI
timescale
 can't set
UTCoffsetValid
flag
 can't indicate
pending leap
NTP:
 can't indicate
pending leap
IRIG1344/C37.118:
 can't indicate
pending leap
Manually set:
 utc offset
 pending leap
IRIG is presumed
to always supply
UTC timescale.
IRIG "no
year"
 No UTC
offset from
TAI
 No Current
year
 No pending
leap
PTP:
 can't set TAI
timescale
 can't set
UTCoffsetValid
flag
 can't indicate
pending leap
NTP:
 can't provide
UTC time
 can't indicate
pending leap
IRIG1344/C37.118:
 can't provide
UTC time
 can't indicate
pending leap
Manually set:
 utc offset
 pending leap
 current year
These IRIG codes
are a subset that do
not provide the
current year. For
standard coding of
IRIGs, the codes
that lack year have
last digit in the
range 0 - 3. If range
is 4 - 7 the year is
provided. For
example, B000 -
B003 do not
provide year, B004
- B007 provide
year.
