如何计算两个日期时间之间的时间差？

from datetime import datetime

start_time = datetime(2022, 1, 1, 12, 0, 0)
end_time = datetime(2022, 1, 1, 13, 30, 0)

time_difference = end_time - start_time
print("时间差:", time_difference)

import java.time.Duration;
import java.time.LocalDateTime;

LocalDateTime startTime = LocalDateTime.of(2022, 1, 1, 12, 0, 0);
LocalDateTime endTime = LocalDateTime.of(2022, 1, 1, 13, 30, 0);

Duration timeDifference = Duration.between(startTime, endTime);
System.out.println("时间差: " + timeDifference);

const startTime = new Date(2022, 0, 1, 12, 0, 0);
const endTime = new Date(2022, 0, 1, 13, 30, 0);

const timeDifference = endTime - startTime;
console.log("时间差:", timeDifference);
