*view: avoid leading zero in time display of the hour
Avoid the visual noise entirely by using a space instead.
I sometimes have difficulty distinguishing '0' from '8' while
other users may mistake it for an 'O' character. Most digital
clocks I've seen will omit displaying a leading zero for the
hour, too.
This may also save transfer time by allowing better compression
(since there is a space between the date and time anyways) and
perhaps reduce client rendering time on some displays.
We'll leave the leading zero for minutes since that seems pretty
standard for digital clocks.
