Summary: test_imaplib broken on Mac

Initial Comment:
Test_imaplib recently broke on the Macintosh (or, to be more specific, for MacPython).

The reason seems to be that the test has been modified to check that all 5 test dates (3 in 1967, 2 in 2033) return the same value after a round trip. For MacPython this is true for the 3 1967 values but not for the 2033 values: these are both the same value, but in 2033, which is also what i would expect, really.

Is the 1967/2033 match testing for something that is really part of the imap spec? Or could it be that it is testing a artefact of the Unix implementation of time values (which apparently doesn't occur when using the Metrowerks runtime on MacOS, which has a wholly different representation of time), and that we really shouldn't be testing this? Or testing it and only matching it against itself (i.e. the 2033 time value)?

version 1.2 of test_imaplib.py worked, so should fix this
problem.

(The later versions were an attempt to increase the number
of functions tested, but clearly didn't solve the time-zone
problem. Version 1.2 just tests that there is no exception
for one function, and doesn't attempt to check the output.)

I've reverted test_imaplib.py to version 1.2 which as far as
I know is known to work everywhere.

All 5 dates are supposed to be the same time (Wed May 18 03:33:20 2033 GMT)
The first three are numbers, the second two are IMAP4 INTERNALDATE representations of that time in different 
timezones.

But of course time.time() values are O/S dpendant, so those numbers will only work on O/Ss with 1/1/1970 as the 
epoch..

I've removed the numbers from the test. Please try the new test, it should now be O/S agnostic.
