A.2 SNTP V 3.0 Data Format per RFC-2030

When TimeVault replies to requests from SNTP clients, the packet format is the same as

the NTP packet format described above, with the following differences:

• Leap Indicator

TimeVault sets these 2 bits to either 0 (normal) or 3 (unsynchronized) only

• Version Number

TimeVault copies this field from the client request packet and returns it in this field.

• Reference Timestamp

This field is set to the time that the reply left TimeVault’s server host.

• Receive Timestamp

This field is set to the time that the reply left TimeVault’s server host.

• Transmit Timestamp

This field is set to the time that the reply left TimeVault’s server host.
