Davanum Srinivas (dims) 19d21f65e2 Switch back to iso format on the wire
following change id replaced timeutils.isotime(dt) with dt.isoformat():
Ied2643d3d891600e0e5cd31c7ef1ff6107e3a777

However this change breaks existing contract between Nova components
on the wire, so we need to resurrect a bit of the older code.
