Truncating vs rounding SAS time values

Small matters matter. Imagine saving (or spending wisely) just 1 second of your time every hour. One measly second! During your lifespan you would save or spend wisely (1 sec-an-hour * 24 hours-a-day * 365 days-a-year * 100 years) / (3600 seconds-an-hour * 24 hours-a-day) = 10 days, a whole
