round-down-ymdhms

function

Library: Date and time functions (OMDATE)
Include: omdate.xin

Returns: the specified date/time rounded down to the nearest indicated interval


Declaration 
define string function 
   round-down-ymdhms    value string ymdhms
                     to value string interval

Argument definitions

ymdhms
A date/time in YYYYMMDDhhmmss+ZHZM format.
interval
The name of the interval which you want the indicated date rounded to.


Purpose

round-down-ymdhms takes a date/time in YYYYMMDDhhmmss+ZHZM format, and returns the same value but rounded down to the beginning of an interval indicated by the second argument. Only the shortest distinguishing prefix of the interval name is needed, so y can be used in place of year, but mo and mi are needed to distinguish between month and minute. This argument can be in either uppercase or lowercase. If this argument is unrecognized, the date/time will be returned unchanged.

Example

The following program takes the current date/time, and rounds it down to the nearest minute. 

  include "omdate.xin"
  
  process
     local string now
  
     set now to now-as-ymdhms
     output "Now, unrounded                  = " || now || "%n"
         || "Now, rounded down to the minute = " || round-down-ymdhms now to "mi" || "%n"
Running this example might yield output such as 
  Now, unrounded                  = 20191031155546-0400
  Now, rounded down to the minute = 20191031155500-0400

Usage Note

To use round-down-ymdhms, you must include the following code near the top of your program: 

  include "omdate.xin"
