I think "0 unspecified or unknown" is in the Clock Status Word.
The trap doesn't send that back, it does send Clock Source,
in the System Status Word;
The Clock Source Field displays the current synchronization
source coded as follows:.
Code Message Description
0 sync_unspec not yet synchronized
1 sync_pps pulse-per-second signal (Cs, Ru, GPS, etc.)
2 sync_lf_radio VLF/LF radio (WWVB, DCF77, etc.)
3 sync_hf_radio MF/HF radio (WWV, etc.)
4 sync_uhf_radio VHF/UHF radio/satellite (GPS, Galileo, etc.)
5 sync_local local timecode (IRIG, LOCAL driver, etc.)
6 sync_ntp NTP
7 sync_other other (IEEE 1588, openntp, crony, etc.)
8 sync_wristwatch eyeball and wristwatch
9 sync_telephone telephone modem (ACTS, PTB, etc.)
