Hinweise

The StartTime value must conform to the Microsoft .NET Framework string representation of a DateTime data type. The StartTime value must be specified in UTC.

If you do not provide a StartTime value, Notification Services runs the event provider for the first time when the instance starts or when you enable the event provider.

If you do provide a StartTime value, Notification Services runs the provider as follows:

  • Notification Services calculates the invocation times for the 24-hour period starting at the StartTime value.
  • Notification Services first invokes the event provider at the next calculated invocation time.

The table shows examples of invocation schedules given various StartTime and Interval values.
