TimeDelta

Struct TimeDelta 

Source
pub struct TimeDelta {
    pub offset_ms: i64,
    pub round_trip_ms: u64,
}
Expand description

Measured clock offset and round-trip delay from a single SNTP exchange.

All values are in milliseconds with sub-millisecond resolution.

The classic SNTP offset formula uses four timestamps (RFC 4330 §5):

offset = ((T2 - T1) + (T3 - T4)) / 2
RTT    = (T4 - T1) - (T3 - T2)

where:

  • T1 = client transmit time
  • T2 = server receive time
  • T3 = server transmit time
  • T4 = client receive time

Fields§

§offset_ms: i64

Signed clock offset in milliseconds.

Positive means the local clock is behind the server (local is slow). Negative means the local clock is ahead of the server (local is fast).

§round_trip_ms: u64

Round-trip delay in milliseconds (always ≥ 0).
