[pve-devel] [PATCH v2 common 2/6] format: handle undef, 0, and decimals in render_duration

This might be a "breaking" change for some situations, but I believe this should
be more correct in the long run... If this is not wanted, we must do a ceil() or
similar on the value passed in from patch 4/6, otherwise it will not print a
time value for the first iteration.
