No it shouldn't... check your locale.  For example, en_US:

% Appropriate time representation (%X)
%       "%r"
t_fmt   "<U0025><U0072>"
%
% Appropriate AM/PM time representation (%r)
%       "%I:%M:%S %p"
t_fmt_ampm "<U0025><U0049><U003A><U0025><U004D><U003A><U0025><U0053><U0020>/
<U0025><U0070>"


This tells date that the appropriate time representation for the en_US
locale is exactly what you are seeing.
