Errors in output from formatTime

Hi,

I have discovered two errors in the Date/Time libraries distributed with GHC.

When running the attached testcase:

*Main> timebug
Loading package old-locale-1.0.0.0 ... linking ... done.
Loading package time-1.1.2.0 ... linking ... done.
"Sun, d Apr 2008 00:16:45 UTC"

There are two problems here:

Returns "d" for day of month, certainly not right.
Returns "UTC" instead of "UT", incorrect per RFC 822 - http://www.faqs.org/rfcs/rfc822.html section 5.1
