Create a small function to decrypt UniqueRunID

[fpilo]

// cout<<cUniqueRunId<<" - "<<UniqueRunId1<<" i.e. "
360 // <<" STATIONID "<<(Int_t) (UniqueRunId1/1E9)<<" - "
361 // <<" DAYS FROM EEESTART "<<(Int_t)((UniqueRunId1-(Int_t) (UniqueRunId1/1E9)1E9)/1E5)<<" - "
362 // <<" RUNID "<<(Int_t)(UniqueRunId1-(Int_t) (UniqueRunId1/1E5)1E5)
363 // <<endl;
364 // eventtime = e3starttime + 246060*((Int_t)((UniqueRunId1-(Int_t) (UniqueRunId1/1E9)*1E9)/1E5));
365 // timestr = asctime(gmtime(&eventtime)); timestr[strlen(timestr)-1] = '\0';
366 // cout<<timestr<<endl;
367 // cout<<gmtime(&eventtime)->tm_year+1900<<endl;
368 // cout<<gmtime(&eventtime)->tm_mon+1<<endl;
369 // cout<<gmtime(&eventtime)->tm_mday<<endl;
