Time Delta is a medium difficulty problem that involves datetime manipulation and we have to return the absolute difference between in seconds. We will learn how to solve this problem in Python through a step-by-step tutorial in Python3.
Problem Statement and Explanation
Given two timestamps in the format Day dd Mon yyyy hh:mm:ss +xxxx where +xxxx represents the time zone. We have to print the absolute difference (in seconds) between them.
Suppose the first timestamp is Sun 10 May 2015 13:54:36 -0700 and the second timestamp is Sun 10 May 2015 13:54:36 -0000.
- t1 = Sun 10 May 2015 13:54:36 -0700
- t2 = Sun 10 May 2015 13:54:36 -0000
The absolute difference between them is 25200 seconds because the time zone offsets are -0700 and -0000 and then 7 hours is 25200 seconds. 7 * 3600 = 25200 seconds.
- In the given solution, we will use the
datetimemodule to convert the given string into a datetime object. - Then we will find the absolute difference between them and return the difference in seconds.
Time Delta Solution in Python
| import datetime | |
| def time_delta(t1, t2): | |
| t1 = datetime.datetime.strptime(t1, "%a %d %b %Y %H:%M:%S %z") | |
| t2 = datetime.datetime.strptime(t2, "%a %d %b %Y %H:%M:%S %z") | |
| difference = int(abs(t1-t2).total_seconds()) | |
| return str(difference) |
Time Complexity of the Solution
The time complexity of the above solution is O(1) because we are using the datetime module to convert the given string into a datetime object and then we are finding the absolute difference between them and returning the difference in seconds.
