Module time_sync 

Time synchronization manager for Binance API.

This module provides a thread-safe time synchronization mechanism that caches the time offset between local system time and Binance server time. This optimization reduces the number of network round-trips for signed API requests from 2 to 1.

Overview

When making signed requests to Binance, a timestamp is required. Previously, each signed request required fetching the server time first. With TimeSyncManager, the time offset is cached and used to calculate server timestamps locally.

Example

use ccxt_exchanges::binance::time_sync::{TimeSyncConfig, TimeSyncManager};
use std::time::Duration;

// Create with default configuration
let manager = TimeSyncManager::new();

// Or with custom configuration
let config = TimeSyncConfig {
    sync_interval: Duration::from_secs(60),
    auto_sync: true,
    max_offset_drift: 3000,
};
let manager = TimeSyncManager::with_config(config);

// Simulate receiving server time and updating offset
let server_time = 1704110400000i64; // Example server timestamp
manager.update_offset(server_time);

// Get estimated server timestamp using cached offset
let estimated_server_time = manager.get_server_timestamp();
