My key question to those advocating the use of timedelta instead of Decimal:

What should timedelta.total_seconds() return to avoid losing
nanosecond precision?
How should this be requested when calling the API?

The core "timestamp" abstraction is "just a number" that (in context)
represents a certain number of seconds. decimal.Decimal qualifies.
datetime.timedelta doesn't - it's a higher level construct that makes
the semantic context explicit (and currently refuses to interoperate
with other values that are just numbers).

Cheers,
Nick.
