It depends how you calculate your timestamps, I'd say :-) It's unlikely for two calls to time.time() to give the exact same outcome.

It depends how you calculate your timestamps, I'd say :-) It's unlikely
for two calls to time.time() to give the exact same outcome. OTOH, if
you're using a fixed base time and add user-provided timedeltas to it,
collisions are quite possible.
