Why do we need this as a separate field? As discussed, please use just
|last_policy_refresh_time_|.

[gfeher, 2011/02/28 12:21:32]

Another reason for using this was that SetUnmanaged() is setting this value to
the current time and we don't want to send that value back to the server.

But now I realize that I can filter is_unamaned_ == true before sending the
value. (And in each case when is_unamanaged_ is possibly set to false, then
last_policy_refresh_time_ is updated with a sensible value.)

In short: Done.
