Summary: imaplib.Time2Internaldate is broken

Initial Comment:
The type tests in this function have stopped working
because the return type of time.gmtime() and friends is
now time.struct_time and not tuple.

Secondly, the format string used for the timezone is
'%+02d%02d'.  I believe it should be '%+03d02d' since
the first field width includes the sign character.

A patch that works for me (note that it lets strftime
do its own type-checking):
