pytz difference of 2 datetimes in seconds? (Different time zones)

Question

I have 2 datetime objects with 2 different time zones:

datetime1 = 18:26:23, with tzinfo = UTC

datetime2 = 14:30:00, with tzinfo = US/Eastern

Both dates

Answer 1

There are two likely scenarios here.

1. Either you are creating the timezone on your datetime objects incorrectly
2. The timezone is correct but your datetime objects are not actually representing the time you say they are.

For example, regardless of timezone, I don't see how the diff between 18:26:23 and 14:30:00 could possibly give you an even number of seconds, which makes scenario #2 more likely.

Can you print the value of the datetime objects right before you run the line:

time_diff = (datetime2 - datetime1).total_seconds()

Here is some sample code for reference that gives you the expected seconds:

from pytz import timezone
from datetime import datetime

eastern = timezone('US/Eastern')
utc = timezone('UTC')
datetime1 = utc.localize(datetime(2002, 10, 27, 18, 26, 23))
datetime2 = eastern.localize(datetime(2002, 10, 27, 14, 30, 00))
time_diff = (datetime2 - datetime1).total_seconds()
print(time_diff)  # prints 3817
