Should be > Return the total number of seconds contained in the duration. Equivalent to (td.microseconds / 10**6 + (td.seconds + td.days * 24 * 3600) * 10**6) computed with true division enabled. At least i hope, the bug is only in the docs and not in the function ;).

The docs look correct to me. For example, >>> from datetime import * >>> td = datetime.now() - datetime(1,1,1) >>> td datetime.timedelta(735103, 61756, 484000) >>> td.total_seconds() 63512960956.484 ^ What the docs say match that output: >>> (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 1e6 63512960956.484 Your suggestion's output: >>> (td.microseconds / 1e6 + (td.seconds + td.days * 24 * 3600) * 10**6) 6.3512960956e+16 You're multiplying the number seconds by a million - not a good idea ;-)

Err, sorry my fault. Too late in the evening ;). I saw the division by one million, but not the multiplation by one million before. Additionally i was confused, because i expected that seconds are added to each other in the parenthesis. closing.
