It would be nice if it were possible to deal with high-precision epoch times and time deltas without special tricks. I have had to deal with femtosecond-precision IRL (albeit in a realtime C application, not in Python). Quad-precision floats (<URL: http://en.wikipedia.org/wiki/Quadruple-precision_floating-point_format>) would do it for Python: * just do it in seconds * have enough precision for any needs * have enough renge for any needs Marko _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
