Get current date & time in ISO format

[SmartyPants]

Hi,

I need to grab the current time and date, format it to ISO and add 20 minutes.
I use it for boosting my thermostat which only accepts a temporary setpoint change if the request is combined with a future date.
I don't want to use it with a distant future date like 2080 as I want it to automatically shut off after 20 minutes.

I currently use a script in LUA which works fine but have no clue in vb.net, it could be in vb script but it must be easier in .net
The output needs to be:

2017-06-26T00:00:00.00Z

Thanks

Sub Main(ByVal Parms As String)

    Dim tm As DateTime = DateTime.Now.AddMinutes(20)
    'Dim tmiso As String = tm.ToString("o")
    Dim tmiso As String = tm.ToString("yyyy-MM-ddTHH:mm:ssZ")
    hs.writelog("Time ISO",tmiso)

End Sub

The first one which is remarked out would provide the output with milliseconds.

If you want the time in UTC change the first line to:

Dim tm As DateTime = DateTime.UtcNow.AddMinutes(20)

I sometimes think you're the only one on these forums Jon.
I'm also beginning to think you work for HST as you spend so much time here

Thanks for this. I actually got the time part sorted last night and came up with almost the same.
But I was trying to use TimeSpan to add minutes which get causing errors the way i tried it.

Anyway thanks.
