SPSS date, time and datetime variables are shown in a nice and readable format such as “8-Jan-2013 16:56:10”. However, they all contain just numbers of seconds.
This may sound daunting at first but soon turns out to make all sorts of time manipulations surprisingly easy. It also implies that most SPSS date functions can be used on date, time and datetime variables in the exact same way. In some cases, you won't even bother about these functions and just use simple additions and subtractions for time calculations.
After studying the tutorials listed below, you'll wonder what people could possibly find difficult about time and datetime in SPSS. Enjoy!
