CRM 2011 – Dialog Date and Time Response type error

I was creating a dialog today and came up  against a very odd and annoying error.  I talk about it in this Hosk CRM Dev video or you can read the blog below.

I was trying to get an response of type Data and Time.  I thought I would be clever and default the time to the current time by using the Process –> Execution time.

Below you can see the values I have used

but then when I tried to run the dialog and got this error

and below you can see the error which was being thrown

I couldn’t understand why it was throwing an error.  Logically it didn’t seem to make sense and the error message.

So I thought perhaps if I added one minute to the time this would then work and hey presto it did as you can see below

 

So the moral of this story is, if something doesn’t work add a minute to it and who knows why that works
