Example
Imagine you wish to generate an event containing the current time and send it to an Email sink unit.
You can use the Start unit to emit an event with the current time. To do this, we add a Start unit to fire out an event and link it to the in input port of an Email sink unit to send it to the required recipients.
In order to glean the current time, you must simply set a name for the Time field. By filling in this field, a field with the current time is generated in the output event.
In the Email Sink unit properties, specify the email to send the events to in the to recipients tab.
