Import number as time

shellp55 — Thu, 23 Jul 2009 23:29:52 GMT

Hi

I am using SAS 9.1 and importing a .txt file using infile and input statements. I am then exporting the file to an MS-Access database.

I've got everything figured out except the time fields. Each time field in the file is in a time increment of a 24 hour clock but without the colon i.e. 2130, 1055, 1544. How do I import so that SAS recognizes it as a time? What format do I then use upon export?

Thanks for any and all assistance.

No std informat i think to read such a time. You have to tweak it a bit.

x='2130';
sastime=input(x,2.)*3600+input(substr(x,3,2),2.)*60;
or
sastime=input( substr(x,1,2)||':'||substr(x,3,2)||':00', time.);

The export format will depend on what Access wants. time. or hhmm. would seem adequate.

For more structured support, use the HMS function after reading up the components of the hour and minute portion - example below:

data _null_;
input hh 2. mm 2.;
time = hms(hh,mm,0);
put time= time5. ;
datalines;
2359
run;

Indeed, Scott's suggestion to let the hms function do the calculation is a bit tidier. You now have:

x='2130';
sastime=input(x,2.)*3600+input(substr(x,3,2),2.)*60;
or
sastime=hms( input(x,2.), input(substr(x,3,2),2.), 0);
or
sastime=input( substr(x,1,2)||':'||substr(x,3,2)||':00', time.);

So many ways with sas! 🙂

But if I have a :

105 (time: 01:05)

how can I do?

well, it will be more easier in excel
change it in excel 105-> 0105

Forum posting Suggestion: next time create a new post as you being the AUTHOR, and paste a link if needed back to some forum archive reference.

With SAS 9.2, you have the ISO 8601 INFORMAT B8601TM demonstrated below.

Otherwise, you will need to separate the minute- and hour-portion and use the HMS function to derive a SAS numeric TIME variable.

68 data _null_;
69 c_hmm = '105';
70 n_hmm = input(c_hmm,best.);
71 c_hhmm = put(n_hmm,z6.);
72 n_hmm_sec = input(c_hhmm,b8601tm.);
73 format n_hmm_sec time8.;
74 putlog _all_;
75 run;

c_hmm=105 n_hmm=105 c_hhmm=000105 n_hmm_sec=0:01:05 _ERROR_=0 _N_=1
