This is discussed in Issue 6280 <http://bugs.python.org/issue6280>.
There are several issues with this proposal:

1. According to help(time),

"""
    The Epoch is system-defined; on Unix, it is generally January 1st, 1970.
    The actual value can be retrieved by calling gmtime(0).
"""

Current calendar.gmtime implementation ignores this.  The solution to
this, may be to change help(time), though.

2. Current calendar.gmtime supports float values for hours, minutes
and seconds in timedelta tuple.  This is probably an unintended
implementation artifact, but it is relied upon even in stdlib.  See
