如何找出两个熊猫时间戳之间的所有唯一小时？

import datetime

def find_unique_hours(start_timestamp, end_timestamp):
    start_datetime = datetime.datetime.fromtimestamp(start_timestamp)
    end_datetime = datetime.datetime.fromtimestamp(end_timestamp)
    unique_hours = set()
    
    current_datetime = start_datetime
    while current_datetime <= end_datetime:
        unique_hours.add(current_datetime.strftime('%Y-%m-%d %H:00:00'))
        current_datetime += datetime.timedelta(hours=1)
    
    return unique_hours
