So basically, I want to convert the input in order to determine the proportion of how much time is remaining using the base value of 12:00:00. For example, converting the time input values into seconds, and converting the base value into seconds and dividing the input by the base. I know how to do the math, but the formatting from the data set i was using was throwing me off, and I was confused on how to go about getting the output. I ended up reading up on the timew. informat that can read this and convert it to a value in seconds with the reference being 00:00:00 or 12 AM, which is similar to date informats in sas with days. From this comparison, I was wondering if there was a way to change this reference value with a global option.
