RE: [Xen-API] [PATCH] Add function to Date module to assert ISO 8601 datetime values are UTC

[Rob Hoes <Rob.Hoes@xxxxxxxxxx>]

Ah, thanks for making me aware of that :)

I have attached a new version of the patch.
I now have the function like this:

let assert_utc x =
        try
                Scanf.sscanf x "%_[0-9]T%_[0-9]:%_[0-9]:%_[0-9]Z" ()
        with _ -> invalid_arg x

I think that should do what I wanted.

Cheers,
Rob
