Description 1
NTP Reference Clock Identifier. This is a
32 bit code identifying the particular reference
clock. In the case of stratum 0 (unspecified) or
stratum 1 (primary reference), this is a four-
octet, left-justified, zero-padded ASCII string.
While not enumerated as part of the NTP spec, the
following are suggested ASCII identifiers:
==============================================
DCN DCN routing protocol
NIST NIST public modem
TSP TSP time protocol
DTS Digital Time Service
ATOM Atomic clock (calibrated)
VLF VLF radio (OMEGA,etc.)
callsign Generic radio
LORC LORAN-C radionavigation
GOES GOES UHF environment satellite
GPS GPS UHF satellite positioning
==============================================
The following ref ids are used by the SyncServer:
==============================================
GPS GPS satellite)
IRIG IRIG B timecode
1PPS Ext. 1 PPS input
E10M Ext. 10 MHz input
FREE Internal Clock
FLY Internal Clock after the Hardware
Clock reference is lost
