    Did you read the whole article?

     


    I quote:

    "The returned time period is measured starting from the "zero date", which is 12:00 AM, December 30, 1899. However, if the period is less than one day, then the date portion is omitted. Besides, if your locale uses the 12-hour clock notation, the resulting value is displayed using "before noon" and "after noon" abbreviations (like AM/PM in English).

    Because of these reasons, using the common aqConvert.DateTimeToStr method to display the TimeIntervalresults could yield quite odd results (like 12/31/1899 12:00:05 AM when the difference is 1 day and 5 seconds). This could be rather confusing for the values that reflect time duration. To avoid misunderstanding, it is better to use the dedicated method, TimeIntervalToStr, that returns a string in the D:HH:MM:SS format, which indicates the time passed since the "zero date"."

     

     

    So... change your code to the following:


     

    I tried this.
var currentdate = aqDateTime.Now();
var newDate = aqDateTime.AddDays(currentdate,3);
 
var res = aqConvert.TimeIntervalToStr(aqDateTime.TimeInterval(currentdate, newDate));

Log.Message('The interval is ' + res);

    If you specifically want to peel out the days only, use res.split(':') to return an array of the string where the first element in the array is the number of days.

Hi tristaanogre,

 

I tried this.

var currentdate = aqDateTime.Now();

var newDate = aqDateTime.AddDays(currentdate,3);

 

var res = aqDateTime.TimeInterval(currentdate, newDate);

 

if I log this, I will get 1/2/1900 20:27:57

Log.Message("The interval as DateTime: " + aqConvert.DateTimeToStr(res));

 

What I want is the days difference which is 3 days (from Dec 30 1899 to Jan 2 1900)

How to get that 3?
