[Cbc] Cbc Digest, Vol 75, Issue 7

Alexis,

getCurrentSeconds() returns time since CbcStartSeconds was set. If unset 
then it is set when branchAndBound is entered.  Otherwise it can be set by

   model.setDblParam(CbcModel::CbcStartSeconds, currentTime);

In the stand-alone solver this normally happens when "solve" is found - 
so time includes any preprocessing time.

Time is normally cpu time - but can be changed to be elapsed time by

model.setUseElapsedTime(true);

so if you had asked for elapsed time, you would initialize time by

     model.setDblParam(CbcModel::CbcStartSeconds, CoinGetTimeOfDay());
