Hackerrank中的时间增量问题没有得到很好的答案/Python 3

hackerbank挑战在以下url中：https://www.hackerrank.com/challenges/python-time-delta/problem

我得到了正确的测试用例0，但网站说我对测试用例1和2的答案是错误的，但在我的pycharm中，我复制了网站的预期输出，并与我的输出进行了比较，结果完全相同。

请看一下我的代码。

#!/bin/pyth
# Complete the time_delta function below.
from datetime import datetime
def time_delta(tmp1, tmp2):
dicto = {'Jan':1, 'Feb':2, 'Mar':3,
'Apr':4, 'May':5, 'Jun':6,
'Jul':7, 'Aug':8, 'Sep':9,
'Oct':10, 'Nov':11, 'Dec':12}
# extracting t1 from first timestamp without -xxxx
t1 = datetime(int(tmp1[2]), dicto[tmp1[1]], int(tmp1[0]), int(tmp1[3][:2]),int(tmp1[3][3:5]), int(tmp1[3][6:])) 
# extracting t1 from second timestamp without -xxxx
t2 = datetime(int(tmp2[2]), dicto[tmp2[1]], int(tmp2[0]), int(tmp2[3][:2]), int(tmp2[3][3:5]), int(tmp2[3][6:])) 
# converting -xxxx of timestamp 1
t1_utc = int(tmp1[4][:3])*3600 + int(tmp1[4][3:])*60 
# converting -xxxx of timestamp 2
t2_utc = int(tmp2[4][:3])*3600 + int(tmp2[4][3:])*60 
# absolute difference
return abs(int((t1-t2).total_seconds()-(t1_utc-t2_utc))) 
if __name__ == '__main__':
# fptr = open(os.environ['OUTPUT_PATH'], 'w')
t = int(input())
for t_itr in range(t):
tmp1 = list(input().split(' '))[1:]
tmp2 = list(input().split(' '))[1:]
delta = time_delta(tmp1, tmp2)
print(delta)
