+	deprecated, but the \%z escape that expands to the preferred 
+	hour/minute offset is not supported by all ANSI C libraries. Also,
+	a strict reading of the original 1982 \rfc{822} standard calls for
+	a two-digit year (\%y rather than \%Y), but practice moved to
+	4-digit years long before the year 2000.}

+>>> from time import *

+'Sat, 27 Jan 2001 05:15:05 EST'
