I think what the user cares about is "what is the smallest tick that this clock result will faithfully represent?". If the number of bits returned is larger than the clock accuracy, you want the clock accuracy. If the number of bits returned is smaller than the clock accuracy, you want the number of bits. (Yes, I'm using accuracy in a slightly different sense here...I think we don't have the right words for this.) To use other words, what the users cares about are the error bars on the returned result. --David _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
