I'm not strong on date formats, but I came up with this suggestion:
I didn't see a built-in SAS date format that you could use, so maybe you can create a picture format using
[pre]
proc format library=work;
picture mydate low-high = '%Y0%m' (datatype=date);
run;
[/pre]
If the date is already in SAS as a date formated value (I think you missed a colon after the year), then you could just apply the picture format . . .
[pre]
data work.date;
format date_in mydate6.;
date_in = '7FEB2008:10:27:59'd;
run;
[/pre]
Then, if the date is literally what you've written, then I would select the date part from this text string and reformat that to the picture format.
[pre]
data work.date;
input date_txt $24.;
format date_new mydate6.;
date_new = input(scan(date_txt,1,"H"), date9.);
cards;
7FEB2008HH:MM:SS
;
run;
[/pre]
