Problems with Date and daysAgo()

[Mikolz]

Hey everyone, having issues with getting the contents of a glide date field and getting the date from 7 days ago.

var date = current.week_starts_on;
var thisTime = date.getGlideObject().toString();
var time = thisTime.setValue(gs.daysAgo(7));
gs.addInfoMessage(time);

Just for testing purposes I am using the info message. I am always getting an error. I think the error is coming from the gs.daysAgo() method. If I remove it and place the variable thisTime in the info mesage it is returning. Seems like everytime I try to work with a datefield there is some special technique that needs to be used...thanks for reading!

No need for setValue(). Just set time = gs.daysAgo(7);

Or I'm just confused as to what you're trying to do.

Thanks for the response, I will explain...So I have a date on a specific form that will always fall on a sunday. I want to take that current date and go back 7 days which would give me last weeks entry. Ultimately, I am going to use the information in glide record.

Gotta love working with glide date and glide date time fields. This gave me what I needed, if anyone cares...

var CurWeekStart = current.week_starts_on.getGlideObject();
var useThisTime = new GlideDateTime(CurWeekStart);

useThisTime.addWeeks(-1);
var finalTime = useThisTime.getDate();

gs.addInfoMessage(finalTime);

SO if the current week on the form is 12-02-2012, this will give me 2012-11-25. Just what I needed...
