A patch to the time functions (ctime, localtime), which allows
them to read in timezones that are four chars long, like CEST.
I did not want to change the output scheme, so the timezones
are read in, but cutted to three chars when printed.

    Thanks for catching this.  Comparing against 
    WET, MET, and EET, I think the intended solution
    is to say CET instead of CEST in the file.
    
    Really the right thing to do is allow and display
    four-char time zones, but I'm not convinced that's
    worth the pain.  I didn't want to go halfway and
    truncate because I know there are some programs
    that assume time zones end in T.
    
    I updated /adm/timezone/CET.
