Note: JMP always displays four-digit years regardless of the regional settings. If you need to show two-digit
years, use character string functions. See the “Types of Data” chapter on page 103.
Date-Time Values in Data Tables
Change Date-Time Input and Display Formats
In data tables, JMP can accept the input of date-time values in one format (the input format), store them
internally as the number of seconds since the base date, and display them in a different date-time format.
The Informat() and Format() functions give you this control.
• In Format() takes a string date-time value, defines the date format used in that string, and returns the
date in ddMonyyyy format.
Informat("19May2011 11:37:52 AM","ddMonyyyy h:m:s");
19May2011:11:37:52
• Format() takes the number of seconds since the base date (or a date-time function that returns that
number) and returns the date in the specified format.
Format(3388649872,"ddMonyyyy h:m:s");
"19May2011 11:37:52 AM"
Format(Today(),"ddMonyyyy h:m:s");
