如何确定当前UTC时间是否至少比给定的UTC时间长12小时？

from datetime import datetime, timedelta

def is_utc_time_longer(current_utc_time, given_utc_time):
    current_time = datetime.strptime(current_utc_time, "%Y-%m-%d %H:%M:%S")
    given_time = datetime.strptime(given_utc_time, "%Y-%m-%d %H:%M:%S")
    time_diff = current_time - given_time
    if time_diff >= timedelta(hours=12):
        return True
    else:
        return False

# 示例用法
current_utc_time = "2022-01-01 12:00:00"
given_utc_time = "2022-01-01 00:00:00"
result = is_utc_time_longer(current_utc_time, given_utc_time)
print(result)  # 输出：True
