Example
Assume that you have created a date/time variable named date1 that contains the following date/time data:
date1=[{!dt, 1992,3,13,10,34,15.000,87474.440,0}, ${!dt, 1983,4,20,12,30,19.000,84224.521,0}, ${!dt, 1964,6,24,16,25,14.000,77350.684,0}]
; To extract each date/time element into a separate variable.
; This procedure creates several variables containing the
; date time data.
DT_TO_VAR, date1, Year=years, Month=months, Day=days
PRINT, 'Years = ', years
; PV-WAVE prints: Years = 1992 1983 1964
PRINT, 'Months = ', months
; PV-WAVE prints: Months = 3 4 6
PRINT, 'Days = ', days
; PV-WAVE prints: Days = 13 20 24
