Converting DateTime to CrmDateTime

It is sometime necessary to convert CrmDateTime type field to DateTime type field and vice versa so that the date and time operations are done swiftly. I happen to have felt this necessity today and wrote this function that converts DateTime To CrmDateTime:

   1:  static public CrmDateTime ConvertToCRMDateTime(DateTime dateTime)

   2:  {

   3:      CrmDateTime crmDateTime = new CrmDateTime();

   4:      crmDateTime.date = dateTime.ToShortDateString();

   5:      crmDateTime.time = dateTime.ToShortTimeString();

   6:      TimeSpan offset = TimeZone.CurrentTimeZone.GetUtcOffset(dateTime);

   7:      string sOffset = string.Empty;

   8:      if (offset.Hours < 0)

   9:      {

  10:          sOffset = "-" + (offset.Hours * -1).ToString().PadLeft(2, '0');

  11:      }

  12:      else

  13:      {

  14:          sOffset = "+" + offset.Hours.ToString().PadLeft(2, '0');

  15:      }

  16:      sOffset += offset.Minutes.ToString().PadLeft(2, '0');

  17:      crmDateTime.Value = dateTime.ToString(string.Format("yyyy-MM-ddTHH:mm:ss{0}", sOffset));

  18:      return crmDateTime;

  19:  }

To get DateTime from CrmDateTime, one can use the Convert.ToDateTime method:

   1:  DateTime tempNextDeliveryDate = CalculateNextDeliveryDate(Convert.ToDateTime(acc.ace_datumletztelieferung.date), acc.ace_lieferzyklus.Value);
