Breakdown DateTime into hour segment in EG

derickloo — Mon, 22 Aug 2016 09:01:18 GMT

I has a table in EG which I which to breakdown the date time into hour segment. The data as below

ID Start Date End Date Task Resource

537 2014-06-27 20:30:00.000 2014-06-28 08:30:00.000 Washing Machine 187

I wish to breakdown the data as below in EG

ID Date Start Time End Time Total Time (Minutes) Task Resource

537 2014-06-27 20:30 21:00 30 Washing Machine 187

537 2014-06-27 21:00 22:00 60 Washing Machine 187

537 2014-06-27 22:30 23:00 60 Washing Machine 187

537 2014-06-28 00:00 01:00 60 Washing Machine 187

537 2014-06-27 02:00 03:00 60 Washing Machine 187

Is it possible I breakdown my data become like that? How can I do this in EG? What function should I use?

Don't know if I read your intentions right, as your suggested result does not consistently follow a rule.

This code:

data have;
infile cards dlm=',';
input id start_date : e8601dt23.3 end_date: e8601dt23.3 Task :$20. resource;
format start_date end_date datetime23.3;
cards;
537,2014-06-27 20:30:00.000,2014-06-28 08:30:00.000,Washing Machine,187
;
run;

data want (keep=id date start_time end_time total_time task resource);
* this just for column order: ;
format id date start_time end_time total_time task resource;
set have;
format
  date yymmddd10.
  start_time end_time hhmm5.
;
start_time = hour(timepart(start_date));
do until (start_date > end_date);
  date = datepart(start_date);
  start_time = timepart(start_date);
  end_time = intnx('hour',start_time,0,'end');
  if date * 86400 + end_time > end_date then end_time = timepart(end_date);
  total_time = round((end_time - start_time) / 60,1);
  output;
  start_date = intnx('hour',start_date,1,'begin');
end;
run;

proc print;
run;

creates this result:

                            start_                total_
Obs     id          date     time     end_time     time          task          resour

How do you know to split it into 30, 60, 60... sections, is that always fixed? If so:

data have;
  id=537; start_date="2014-06-27T20:30:00.000"dt; end_date="2014-06-28T08:30:00.000"dt; task="Washing Machine"; resource=187;
  format start_date end_date datetime.; 
run;
data want; 
  set have;
  date=datepart(start_date);
  start_time=timepart(start_date);
  end_time=start_time+"00:30"t;
  total_time=30;
  output;
  start_date=start_date+"00:30"t;
  do while (start_date <= end_date);
    date=datepart(start_date);
    start_time=timepart(start_date);
    end_time=start_time+"01:00"t;
    total_time=60;
    output;
    start_date=start_date+"01:00"t;
  end;
  format date date9. start_time end_time time5.;
run;

format Date yymmdd10. Start_time End_time time5.

Date=datetime();
Date=datepart(Start Date);
Start_time=hms(hour(Start Date), minute(Start Date),second(Start Date));

End_time=hms(hour(End Date), minute(End Date),second(End Date));
Total_minutes=(End_time-Start_time)/60 ;
