In Minutes, In Hours, In Days, In Weeks, In Years
Converts from the units of the function name to the equivalent number of seconds for the argument.
The argument must be a number or numeric expression. For example, In Minutes(2) yields 120, and In
Years(1) yields 31,557,600 (60 seconds * 60 minutes * 24 hours * 365.25 days).
Date DMY, Date MDY
Accepts numeric expressions for day, month, and year and return the associated JMP date. For example,
Date DMY (20, 3, 1991) and Date MDY(3, 20, 1991) evaluate to 2,752,272,000.
Today

midnight on March 20, 1991 (a Wednesday), the Today function returns 2752272000 (2,752,272,000
seconds) and continues counting. If you evaluate the Today function later in the day, it reflects the
additional seconds.
