SAS (Statistical Analysis System) is a programming language that is used for statistical analysis. It reads data from commonly used spreadsheets, databases and more and provides the output of the analysis in the form of tables, graphs, HTML files, PDF files and more.

Generally speaking, a timestamp is an arrangement of characters that identify when a particular event took place. It usually provides the date and time of the day and is sometimes precise to even a fraction of a second. SAS makes use of types Timestamps for dates that I have explained below:

  1. Date Timestamp: This depicts the number of days between the current timestamp (today) and Midnight (GMT) of January 1, 1960.
  2. Datetime Timestamp: This gives the number of seconds between the current timestamp and Midnight (GMT) of January 1, 1960.

One question that can arise is that why January 1, 1960 was chosen. Well, one story tells us that the SAS founders wanted to use the approximate date of birth of the IBM 370 system. This was a model range of mainframe computers by IBM that were announced as successors to the famous IBM 360 family.

In this article we will be exploring 3 Website to help you to convert SAS timestamps to human readable date.

1. Epoch converter

Let’s move on to the next SAS timestamp converter. This website allows a two conversion which means that you can convert SAS timestamps (datetime) to human readable date as well as the other way round.

To convert SAS timestamps to human date, type or paste the datetime timestamp value in the first box and click on the button ‘SAS Timestamp to Human-Readable’ to get the corresponding date time for GMT as well as your present time zone. You must ensure that you are using the timestamps in seconds, milliseconds, microseconds etc.

To convert human date to SAS timestamp, specify the date and time using the boxes that have been provided, choose the time zone (GMT / local time) and then click on the button ‘Human-Readable to Timestamp’ to get the SAS datetime timestamp in seconds or milliseconds.

All that you must do is type the date or the date and time in the boxes that have been provided depending upon the output that you require. The website will automatically convert the human date to SAS timestamps and display them it real-time.

Unlike the previous website, this one does not allow the reverse conversion from SAS timestamp to human readable date.
