/// Time module - Time-related operations
///
/// This module provides functions for working with time.

/// Get current time in milliseconds since Unix epoch
/// Example: let ms = now_ms()
pub fn now_ms() i64;

/// Get current time in seconds since Unix epoch
/// Example: let sec = now_sec()
pub fn now_sec() i64;

/// Sleep for specified milliseconds
/// Example: sleep_ms(1000)  // Sleep 1 second
pub fn sleep_ms(ms int);

/// Get current timestamp as string (seconds since Unix epoch)
/// Example: let ts = now()  // returns "1700000000"
pub fn now() str;
