Timezone for %t log_line_prefix

If %t is used in log_line_prefix, win32's strftime will print a very 
long timezone information, e.g. "W. Europe Daylight Time" where Linux 
would write "UTC". This makes the timestamp consuming more than half of 
an average line length.
Do we have alternatives to the long form? Do we need the timezone 
information at all? We know already it's the server's time. Another 
alternative would be a short timestamp (%t vs. %T) to have both.
