Struct GlobalTimer 

pub struct GlobalTimer {
    pub base_timestamp: i64,
    pub base_instant: Instant,
    pub last_sync_at: Instant,
}

Core data structure for global timer management

Fields

base_timestamp: i64

Initial timestamp fetched from NTP

base_instant: Instant

Reference point of system clock

last_sync_at: Instant

Timestamp of last NTP synchronization

Implementations

impl GlobalTimer

pub fn new(initial_timestamp: i64) -> Self

Creates a new global timer with the given NTP timestamp

pub fn get_current_timestamp(&self) -> i64

Gets the current timestamp via fast local calculation

pub fn detect_clock_jump(&self, new_ntp_timestamp: i64, threshold: i64) -> bool

Detects if a clock jump occurred by comparing NTP timestamp with internal estimate

pub fn update_timestamp(&mut self, new_timestamp: i64, is_jump: bool)

更新时间戳（处理时钟跳跃或漂移纠正）

pub fn should_sync(&self, sync_interval: u64) -> bool

检查是否需要进行同步
