There are subtle other reasons for that (such as that on Windows, socket file descriptors and os file descriptors are different things). But I'm fine with leaving these in the time module. > Not all functions of the time module are always available. For > example, time.tzset() is not available on all platforms.

Yeah, I think the docs can use some work Maybe from someone interested in contributing to docs specifically? I don't want to make Victor responsible for everything. But the new docs for the time module are a but confusing due to the explosion of new functions and constants. E.g. several descriptions use 'clk_id' without explaining it. Maybe a separate subsection can be created for low-level and/or platform-specific items, leaving the main time module to explain the traditional functions and the new portable functions from PEP 418? -- --Guido van Rossum (python.org/~guido) _______________________________________________ Python-Dev mailing list Python-Dev [at] python http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/list-python-dev%40lists.gossamer-threads.com
