Custom workflow action which returns current DateTime value

Here is the code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Workflow.Activities;
using Microsoft.Crm.Workflow;
using System.Workflow.ComponentModel;
using Microsoft.Crm.Sdk;
using Microsoft.Crm.Sdk.Query;
using Microsoft.Crm.SdkTypeProxy;

namespace CurrentDateTimeWorkflowStep
{
    [CrmWorkflowActivity("Current Date Time", "Utiles")]
    public class CurrentDateTime : SequenceActivity
    {
        protected override ActivityExecutionStatus Execute(ActivityExecutionContext executionContext)
        {
            Value = CrmDateTime.Now;

            return base.Execute(executionContext);
        }

        public static DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(CrmDateTime), typeof(CurrentDateTime));

        [CrmOutput("Value")]
        public CrmDateTime Value
        {
            get
            {
                return (CrmDateTime)base.GetValue(ValueProperty);
            }
            set
            {
                base.SetValue(ValueProperty, value);
            }
        }    
    }
}

And here is the source project and built assembly.
