Time calculation

Former Member over 8 years ago

Hello

I'm trying to calculate date in past: what date was 10 days ago.
I create new Moment and Duration and subtracting them with system errror: Expected Moment.
var Today = new Time.Moment (Time.Today.value())
var Days = new Time.Duration(i * 86400)
var DateInPast = Today.subtract(Days)

All works with function add(), bud subtract() seems to be unable to subtract Duration from Moment.
Any idea?

Which SDK? I seem to recall something like this in the bug reports forum, and i may be fixed in 3.0.0

By the way, you should be able to get around it with this:

var DateInPast = new Time.Moment (Time.today().value()-(i*86400));

Yes, there was a bug with ConnectIQ 2.x where it was not checking for the parameter to subtract() being a Time.Duration. If your app is going to be deployed on devices that could be running the ConnectIQ 2.x SDK, you'll want to use add() with a negative duration:

var DateInPast = Time.today().add(new Time.Duration(Time.SECONDS_PER_DAY * -i));

I'm using the latest SDK 2.4.9 in Eclipse.
But if you were asking for device target SDK, than it is 1.4.
Thanks anyway.

You need to use the workaround since you are targeting devices that will be using versions of the ConnectIQ virtual machine older than 3.0.
