The Essential Guide to SAS Dates and Times
by Derek Morgan
Why does SAS use January 1, 1960, as its arbitrary reference date? How do you convert a value such as 27 January, 2003, into SAS dates? You'll find the answers to these questions and much more in this compact reference that makes it easy to understand how to use and manipulate dates, times, and datetimes in SAS. Novice-to-intermediate users will find the clear, task-focused examples and explanations of formats and functions invaluable; experienced users will appreciate discussions of topics such as intervals and international date and time formats. Included is a bonus "Quick Reference Guide" listing all the formats (with examples) on one handy page.
