# ⨳ convert to a [hhmmss-type integer to a] sas time - (SO) ⨳

April 30, 2013

A few years back, I posted a bit of sample code which converted YYYYMMDD-type integers into proper SAS date values; it’s been the most-viewed page since then. At the time, I thought about doing a HHMMSS-type-integer-to-proper-SAS-time-value as well, but I was in a hurry and, to be honest, never really dealt with time-sensitive data.

Not much has changed, but a recent post on SO pushed my button, so here goes.

I took a slightly different (better?) approach since there were no obvious HHMMSS.SSS informats available (as stevepastelan points out, B8601TMw.d would work). Rather, I simply used the PRXCHANGE function to insert colons in the right spot (161058.262 --> 16:10:58.262), then used the TIMEw.d informat to get a proper SAS time value (16:10:58.262 --> '4:10:58.2't).

data _null_;
input int_val $10.; format time_val timeampm15.3; time_val = input(prxchange('s/(\d?\d)(\d\d)(\d\d\.\d\d\d)/$1:$2:$3/',-1, int_val), time10.3);
put int_val
@15 time_val timeampm15.3
@30 time_val 10.3;
datalines;
000000.001
012345.678
12345.678
161058.262
235959.999
run;


from the log:

000000.001    12:00:00.000 AM     0.000
012345.678     1:23:45.600 AM  5025.600
12345.678      1:23:45.670 AM  5025.670
161058.262     4:10:58.200 PM 58258.200
235959.999    11:59:59.900 PM 86399.900


Note the leading 0 is optional for the 0-9 hours. Also, I’m not really sure what’s going on with the dropped hundredths and thousandths of a second (possibly something with how SAS stores values?), but for my purposes, it works.
