The following code example shows a few simple methods you can use to add and subtract from a datetime variable.

using System;
using System.Reflection;
using System.Runtime.CompilerServices;
namespace Microsoft.Crm.Platform.Workflow
{
   public class BuildIn
   {
      public DateTime AddDateTime(DateTime dt, int years, int months,
                                   int days, int hours, int minutes )
      {
         return dt.AddYears(years).AddMonths(months).AddDays(days)
     .AddHours(hours).AddMinutes(minutes);
      }       public DateTime SubtractDateTime(DateTime dt, int years, int months,
                                       int days, int hours, int minutes )
      {
         return dt.AddYears(-years).AddMonths(-months)
     .AddDays(-days).AddHours(-hours).AddMinutes(-minutes);
      }
   }
}
   

The following shows an example workflow configuration file that corresponds to the sample code.
