比较datetime+millisecond和currentime之间的时间

from datetime import datetime, timedelta

# 获取当前时间
current_time = datetime.now()

# 创建datetime对象
datetime_with_millisecond = datetime(current_time.year, current_time.month, current_time.day, current_time.hour, current_time.minute, current_time.second)

# 添加毫秒数
datetime_with_millisecond += timedelta(milliseconds=500)

# 比较时间
if datetime_with_millisecond > current_time:
    print("datetime+millisecond时间晚于currentime时间")
elif datetime_with_millisecond < current_time:
    print("datetime+millisecond时间早于currentime时间")
else:
    print("datetime+millisecond时间与currentime时间相同")
