newbie first post on this list, if what follows is of context ...
I'm struggling with issue per the subject, read different threads and issue http://bugs.python.org/issue15443 that started 2012 still opened as of today.
Isn't there a legitimate case for nanosecond support? it's all over the place in 'struct timespec' and maybe wrongly I always found python and C were best neighbors. That's for the notional aspect.
More practically, aren't we close enough yet with current hardware, PTP and the likes, this deserves more consideration?
Maybe this has been mentioned before but the limiting factor isn't just getting nanoseconds, but anything sub-microseconds wont work with the current format. OpcUA that I was looking right now has 10-th us resolution, so really cares about 100ns, but the datetime 1us simply wont cut it.
