"""Time Delta Solution """


# -----------------------------------------------------------------------------
# You are givent two timestams in the format: Day dd Mon yyyy hh:mm:ss +xxxx
# where +xxxx represents the timezone.

# Input Format:
# The first line contains T, the number of test cases.
# Each test case contains two lines, representing the t1 and t2 timestamps.

# Constraints:
# input contains only valid timestamps.
# year is  < 3000.

# Output Format:
# Print the absoulte diffrence (t2 - t1) in seconds.

# Sample Input:
# 2
# Sun 10 May 2015 13:54:36 -0700
# Sun 10 May 2015 13:54:36 -0000
# Sat 02 May 2015 19:54:36 +0530
# Fri 01 May 2015 13:54:36 -0000

# Sample Output:
# 25200
# 88200
